ELECTROCHEMICAL STRUCTURE

摘要

A novel anode structure for making a proton exchange membrane fuel cell (PEMFC) tolerant to incidences of cell reversal, said anode structure comprising an electrocatalyst layer wherein said electrocatalyst layer comprises at least one electrocatalyst and at least one proton conducting polymer, characterised in that one or more water retaining material(s) are embedded within the electrocatalyst layer, and a process for the preparation thereof is disclosed. Also disclosed is a novel electrocatalyst ink for use in the preparation of the novel anode structure.
