A comb-like ionomer based on poly(2,6-dimethyl-1,4-phenylene oxide) for the use as anodic binder in anion-exchange membrane direct methanol fuel cells

Alkaline membrane fuel cells: anion exchange membranes and fuels

“…The same membrane in a methanol fuel cell was also studied by the same group 198 with a different bimetallic catalyst, Pd 3 Ag/C, which achieved a lower power density of 11.9 mW cm À2 at 60 C when 2 M methanol with 2 M KOH was used as the anode feed. Jurzinsky et al 199 also obtained a power density of 14.3 mW cm À2 at 60 C with the same membrane in a fuel cell operating on 4 M methanol Pt/C with a comb-like ionomer anode catalyst and Pt/C on the cathode with oxygen feed. Kim et al 50 tested a Tokuyama AEM and obtained a power density of 6.8 mW cm À2 at ambient temperature with a Pt/C cathode and PtRu/C anode catalyst with 1 M methanol and 1 M KOH fuel.…”
