Polymer electrolyte membrane (PEM) electrolysis is the electrolysis of water in a cell equipped with a solid polymer electrolyte (SPE) that is responsible for the conduction of protons, separation of product gases, and electrical insulation of the electrodes. The PEM electrolyzer was introduced to overcome the issues of partial load, low current density, and low pressure operation currently plaguing … WebApr 6, 2015 · anode layers. The porous transport layer (PTL) is made from sintered titanium via a powder metallurgy process. This process allows us to adjust the compaction pressure to get the desired porosity in the PTL (in this analysis, porosity is assumed to be 30% by volume). The CCM and PTL represent the so-called membrane electrode assembly (MEA).
