IONOMER IMPREGNATION OF ELECTRODE SUBSTRATES FOR IMPROVED FUEL CELL PERFORMANCE

摘要

Liquid feed fuel cell performance can be increased by impregnating electrode substrates with a proton conducting ionomer prior to incorporation of the electrocatalyst, and optionally also after application of the electrocatalyst. Ionomer impregnation is particularly effective for direct methanol fuel cell anodes that comprise carbonaceous substrates.
