Electrode ink for membrane electrode assembly

摘要: A composition comprising (a) catalytically-active particles, (b) an organic compound having a pKa of at least about 18 and basicity parameter, β, less than 0.66, (c) polymeric binder. Also described is process for preparing membrane/electrode assembly, which comprises the sequential steps (i) applying layer invention to solid polymer electrolyte, carbon fiber paper, or release substrate; (ii) heating under conditions sufficient volatilize 95 percent component (b); (iii) positioning in contact with if was not applied directly forming assembly thereby. It has been discovered that invention, when used prepare membrane electrode (MEA) provides MEA relatively high voltage given current density gas flow rate fuel cell.
