Water-retaining anode structure for a fuel cell

摘要

A novel anode structure for making a proton exchange membrane fuel cell (PEMFC) tolerant to incidences of cell reversal includes an electrocatalyst layer having at least one electrocatalyst and at least one proton conducting polymer. The anode structure also includes one or more water retaining material(s), such as carbon nanofibers, embedded within the electrocatalyst layer.
