ABSTRACT
A new type of water electrolysis is implemented using an alkaline polymer electrolyte (APE) and non-precious metal catalysts, working only with pure water. The membrane–electrode assembly (MEA) fabricated by sandwiching a self-crosslinking quaternary ammonia polysulfone (xQAPS) membrane between Ni–Fe anode Ni–Mo cathode, both impregnated xQAPS ionomer. Such initial prototype APE has exhibited decent performance comparable to that the well-developed electrolyzer.
