Abstract
Electrodes for an alkaline fuel cell are disclosed. The electrodes include a porous substrate and a catalyst layer supported on the substrate. The catalyst layer includes catalyst particles for catalyzing the electrochemical reaction occurring at the electrode, a hydrophobic binder for providing a network of hydrophobic gas passages communicating with the catalyst particles and hydrophilic catalytically inactive particles for providing a network of liquid transport pathways through the catalyst layer. The liquid transport pathways improve liquid transport through the catalyst layer and electrodes of the present invention provide improved resistance to electrode flooding and electrolyte pumping.
