Abstract
An improved fuel cell anode structure comprises a substrate and a first carbon-based component. The first carbon-based component exhibits little or no resistance to corrosion. When said anode structure is incorporated into a membrane electrode assembly, the membrane electrode assembly is tolerant to incidences of cell voltage reversal.
Claims21
In a fuel cell anode structure comprising a substrate, a first carbon-based component comprising a first carbon material, and a second carbon component, said second carbon component being substantially more resistant to corrosion during cell reversal at fuel cell operating temperatures than said first carbon-based component, the improvement comprising:
- said first carbon-based component having substantially no resistance to corrosion during cell reversal at fuel cell operating temperatures and said first carbon material having a BET surface area of at least 35 m2g−1.
