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has areas of different catalytic activity levels, that is, an area in which the regular catalytic metallic phase has been replaced by a catalytic metallic phase with low catalytic activity whereby the methane vapor reforming reaction is delayed in the areas of reduced catalyst activity.
[ What is claimed is:] [1.] A high temperature fuel cell structure comprising: an anode substrate having a thickness of 0.5 to 5 mm so as to be self-supporting, a catalytically active metallic electrolyte layer formed on said anode substrate, a bi-polar plate disposed on said electrode layer of said anode structure and having fuel passages extending therethrough along said electrolyte layer and including entrance and exit areas, said catalytically active metallic electrolyte layer having in said entrance area a catalytic activity which is lower than the ...
