Abstract
Electrodes for an acid fuel cell are disclosed. The electrodes include a porous substrate and a catalyst layer supported on the substrate. The catalyst layer includes catalyst particles, 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 passages throughout the catalyst layer. The electrodes provide improved resistance to flooding and pumping and may be operated at high current density without developing severe concentration polarization.
