Abstract
In an anode structure for a high temperature fuel cell which has a non-catalytic phase and a catalytic phase with respect to methane-vapor reforming reactions, a substrate with a bi-polar plate disposed thereon has areas of different catalytic activity levels, that is, an area in which the regular catalytic metallic phase has been replaced by a catalytic metallic phase with low catalytic activity whereby the methane vapor reforming reaction is delayed in the areas of reduced catalyst activity.
