Abstract

La présente invention a trait à une pile à combustible à base d'acide formique comportant une solution de combustible à base d'acide formique en communication avec une anode (12, 134), un comburant en communication avec une cathode (16, 135) en liaison électrique avec l'anode, et un catalyseur anodique comportant du palladium. Un mode de réalisation représentatif d'un ensemble d'électrode à membrane de pile à combustible à base d'acide formique (130) comporte une membrane productrice de protons (131) présentant des première (132) et deuxième (133) faces opposées, un catalyseur cathodique sur la deuxième face de membrane, et un catalyseur anodique comportant du palladium sur la première face.
