Abstract
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.
Claims9
An 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, at least one proton conducting polymer, and carbon nanofibres, and wherein the at least one electrocatalyst is supported on macroscopic conductive carbon particles.
