Abstract
A method is described for improving the performance of fuel cells such as H2/air PEM fuel cells and direct methanol fuel cells. It has been discovered that H2 evolution can significantly improve the performance of air cathodes and direct methanol fuel cell anodes. The improvement of air cathodes applies to both H2/air PEM fuel cells and direct methanol fuel cells.
