Homemade iridium oxide catalyst

MEAs tested so far, had established that use of Ft/C catalysts on the anode reduced the performance of the SPE electrolyzer. In addition flow rate had been optimized, trends with temperature were observed, the effect of using alternative proton conducting membrane on SPE performance, and a suitable carbon-based GDL had been demonstrated. The use of a titanium fiber based GDL was identified as an option to optimize SPE performance via judicious selection of material components that make up the system. MEA 42 was assembled using a proton conducting membrane from GEEC (GEEC 117), commercial iridium oxide catalyst on the anode and titanium fibers GDL on both anode and cathode side. In contrast, MEA 51 was made with a homemade iridium oxide catalyst on the anode, Bekinit GDL on the anode and...
