电解槽

  能源系统的燃料电池技术需要一个可靠的氢基础设施。 目前,氢气产生主要是通过从化石燃料的开采。 不过,这可能改变未来将成为电解时作为一种手段来生产氢气突出。

  

  质子交换膜的名称是来自所使用的电解质是质子导电聚合物膜。 质子交换膜质子交换膜**或聚合物电解质膜。 在膜双方都涂有一层薄薄的催化材料。 这两个层次构成了电解槽的消极和积极的电极。

  电解是水分解成氢气和oxygen.Electrolysers基本上由一个消极的和积极的电极和电解质一样。 质子交换膜电解的特点是非常简单,结构紧凑。

  质子交换膜电解分解成氢气和氧气的纯净水。

  当直流电压适用于燃料电池阳极的水分子氧氧化为电子和质子,而被释放。 质子(氢离子)通过一个质子导电膜,以减少他们的位置,纳入电子电路从外部向阴极氢气。 在这个过程中,氧气积聚在阳极。

  An energy system based on fuel cell technology requires a reliable hydrogen infrastructure. At present, hydrogen is produced mostly through extraction from fossil fuels. However, this might change in the future when electrolysis will become prominent as a means to produce hydrogen.

  

  The name PEM is derived from the electrolyte used which is a proton-conducting polymer foil. PEM stands for Proton Exchange Membrane or Polymer Electrolyte Membrane. Both sides of the membrane are coated with a thin layer of catalyst material. These two layers form the Electrolyser's negative and positive electrode.

  Electrolysis is the decomposition of water into hydrogen and oxygen.Electrolysers essentially c**ist of a negative and a positive electrode as well as an electrolyte. PEM Electrolysers are characterized by their very simple and compact c**truction.

  PEM Electrolysers decompose pure water into hydrogen and oxygen.

  When a DC voltage is applied to the fuel cell water molecules at the anode are oxidized to oxygen and prot** while electr** are released. The prot** (H+ i**) pass through a proton-conducting membrane to the cathode where they are reduced to hydrogen gas by incorporating electr** from the outer circuit. In the process, oxygen gas accumulates at the anode.
