Optimization of parameters for hot-pressing manufacture of membrane electrode assembly for PEM (polymer electrolyte membrane fuel cells) fuel cell

A Review on Membranes and Catalysts for Anion Exchange Membrane Water Electrolysis Single Cells

“…To obtain high performance AEMWE, MEA optimization should be performed in tandem with material development so as to achieve facile electrochemical reactions. For example, extensive research has been conducted to optimize the MEA performance in PEM fuel cells, with many variables investigated such as the ionomer content in the catalyst layer [77][78][79][80], the catalyst layer structure [81][82][83], and the pressing conditions in the MEA fabrication process [84][85][86][87].…”

Assemblies of protective anion exchange membrane on air electrode for its efficient operation in aqueous alkaline electrolyte

“…As the air electrode is a porous medium, it is highly sensitive to the clamping pressure: the thickness, the porosity and permeability of the MEA change with the applied pressure, thus modifying the electrochemical performance. For instance, Okur et al [11] optimized recently the parameters of assembly for a fuel cell by taking account of the manufacturing cost and difficulties in operating conditions. The maximum power density was obtained when assembly is carried out at 97 C for 3.6 min and at 66 kg cm À2 pressure.…”

The preparation and application of a low-cost multi-channel tubular inorganic–organic composite microfiltration membrane

“…The complicated preparation procedure especially the high temperature sintering process often leads to a high manufacture cost and restricts the application of ceramic membranes. Against that, organic polymeric membranes can be easily prepared through solution casting [18] or hot press methods [19], and the membranes structure can easily be fine-tuned through controlling the parameters such as concentration, evaporation and gelation processes. The production cost is very low and the obtained membranes possess all the desired advantages, such as high selectivity, diverse variety, and manageable pore structure [20].…”
