NEW NANOMETRIC CATALYSTS FOR PEM* ELECTROLYSIS
Water electrolysis is the hydrogen production process that potentially has the lowest environmental impact. The development of low-temperature electrolysis is hampered by the limited resources of iridium, which is the fundamental component needed to break down water under operational conditions for PEM electrolysis. The MOISE project aims at improving the mass activity by a factor of 5 compared with IrO2 by reviewing the architecture of the anode. The recommended approach consists in dispersing iridium oxide on a nanometric scale on a catalyst support made of doped tin dioxide.
