警告!在氢燃料电池的制造及使用过程中,存在一定危险因素和潜在致命后果,如果你不做必要的预防措施,将是一项非常危险的活动,所以大家在制作过程中一定要注意危险,后果自负!

Hi guys ...been a long time sine I wrote here eh? Well you're looking at the same plate assembly that I used in the Wal-Mart containers, but now they're flipped on their sides. I cut off the long "legs" that were extending upwards to the lid of the containers since these are now going to sit on their sides. Why? Because I found what I believe to be a much better Wal-Mart container  

Just another angle so that you can see I kept the exact same spacing. I used 2 nylon washers from Fastenal --the place where I purchase my #316 stainless stuff and nylon items.

This is a top-down view of how the plates fit inside of the new containers. You can see that they are nearly a perfect fit. 6 x 3 inches. The containers are about 12 inches tall so I have a LOT of water over the top of these plates which adds a LOT of extra safety to the setup.

I'm coming throught he sides with a TOPOGEE type seal. Many thanks to Bill for cutting these out for me. He gets the stuff for the boiler work that he does.

The are 2 side by side. I have enough plate assemblies to make 5 total right now. That should be enough to start testing.

Nice PIC from the side of the new reactors. The water level is FAR above the plates so there is never any exposed metal in this new design.

Just a few more angles for you.

Yet another one so that you can be sure to see what I've done.

I used some older electrolyte so the discoloration is from that; not from the new setup.

Here's the lid of one of the Walmart Cereal containers. It's very hard to see but I put Goop Glue all around the inside lid. I did this a very specific way to help ensure a tight seal. I opened the lid first the whole way. I then started squeezing the glue container while nipping off little globs of glue all around the inside rim. This made a bunch of little joined blobs all around the inside edge of the lid.
I then closed the lid which further smooshed and distributed the glue evenly along the entire lid. This gave a very good seal on the lid and I am hopeful that it will withstand quite a bit of pressure before popping opened. In fact I hope that this seal never pops open really.

Here are 2 of the lids in place, just to show you how I'm doing it. You'll notice that NOTHING is attached to the lids. Now why is that you may ask?
So right, you're probably dying to know why I did so many of the odd things that I did with this design. Well it's too late to go into it all right now. I need to get to bed, but I will work on that novel tomorrow. I'll explain everything about why I carefully chose the design that I have this time around. I'll go into why it is so much more superior to my prior designs and I will tell you the direction I'm going with this new work.
For now you'll have to wait in anxiety  Study the pics and pick up clues as to what I might be up to! -If you care to study them that is.

4/13/2005 --OK I wrote some more for you, but have not yet had time to get more work done and take more pictures. For now this is what I have to offer. I'm sorry it's not more at the moment:
I have 12 plates each 3x6 so I'm loosing the equivelent of a 6x6 area in each of these cells. If you really get picky you are probably not loosing the entire 3x6 area as it does react, just not as much as the rest.
But the advantages that Bob started alluding to ...that's where I'm headed. You see with this design you get a TON of advantages. I'll list them now and then I'll go post this information on my project page:
-Unlimited water reserve
-No current leakage or short circuiting.
-Water sloshing is no problem at all.
-Heat buildup is next to nothing.
-Pretty much explosion proof if built properly.
-Very cheap to build
-Much safer (goes along with explosion proof)
-Far less contained gas in the electrolyzer
-Cells are all isolated from each other
-Easily runs from a 12v source
-Water level is not critical in this design
Sound too good to be true? Read on and I'll fill you in...
With a submerged plate array you can have the plates under 100 feet of water if you like ...their depth is only limited by the container itself. There is no current leakage or short circuiting between cells since you never have to worry about about frothing and bubbles bridging across several plates which happens often in a series cell design.
Sloshing is no problem. You can put these right into a vehicle with no problem. Since the plate arrays are submerged, water sloshing above the plates is no longer an issue. It won't do anything to harm the cell. At most you may get some water into your gas line but that will simply be pushed up into the bubbler and no harm done really. On the other hand, in the series cell design, water sloshing was a HUGE problem.
Heat buildup is next to nothing in this design. You have so much water surrounding the plates that you never really have to worry about Delta T changes in your heat from one end to the other end of your electrolyzer. Heat is little to no concern in this design.
Explosion proof if built properly. This is a HUGE thing that I've been thinking of for a very long time. I'm building these cells to NOT have anything at all coming out their tops. I'm purposely building the tops to blow off in the event of a backflash into the cells. Long ago I built my first true electrolyzer cell out of 1 inch PVC. It was about 2 feet tall. I ran a torch tip right off of the cell itself (yes I have pictures of it in the first 6 pages of my electrolyzer project). Whenever I had a backflash in that little guy, the top would pop right off and no harm done. I'd push it back on and light the torch again. The cell never even had to be shut off! -Believe it or not The plates just kept happily running below the water line. The electrolyzer was not harmed or damaged in any way at all since the TOP was the weakest link in the design. This fortunate little accidental design feature has seeded my ideas for these new designs. Build the top to simply POP off in case of a backflash! -Yes this means that you'd have to be careful in a true production model, to not build up too much pressure, but I bet with proper glueing, you'd be able to hold 15 PSI no problem. -I'll just have to experiment and see.
Very cheap to build... I don't think you could get much cheaper than this. 4 bucks per cell container and these containers are very nice. They're strong, crack resistant, chemical resistant, virtually clear and just he right size! If you purchased 10 of them (12v / 10 cells) you would have 1.2 volts per cell.
With this design you can keep far less gas in the top of your electrolyzers. You can do this because you can have the water filled up to the tippy top where before in the series cell design, I had to keep the water level below the tops of the plates.
You can have a much larger range between your high and low water levels. If you don't mind getting extra gas building up in the top of your electrolyzer, you can actually let the water level drop inches if you want to be that foolish The cell will not care one bit and production will not change at all.
Easily runs off of a 12v source. Before in the series cell design you had to have a LOT of plates to give you the required surface area to produce the necessary gas volume. In this design, you can have as much plate surface area as you like without need for expensive cells. That means you can pump MASSIVE amperage through this system to get the output that you desire. Can anyone raise your hand when you think of something that puts out massive amperage at 12v ? Hmmm
Car Batteries, Alternators ...those seem like pretty good answers!
So what's all this amount to? -Nothing if you are just doing standard electrolysis. Well not exactly nothing. It amounts to a much safer electrolyzer design in my opinion and it should make things a lot easier and cheeper to build. No need to go to a custom plastics shop and have PVC welded up into a box for $500 bucks! ouch!
If on the other hand we find the special frequencies to literally rip the water apart as I firmly believe exist, we have an incredible system here that can be readily incorporated right into your vehicle. Put this into your trunk and you're all set. No special transformers or invertors, no special anti-sloshing mechanisms. No difficult challenges with maintaining tight water levels in a moving vehicle. No sir this would be a veritable joy to install ...if you of course found those frequencies
So I'll go back down and do some more work and get you guys some more pictures. Time has been limited lately so my apologies
I hope this information was worth the wait? Please let me know!
