RIBBED SUBSTRATE FOR FUEL CELL ELECTRODE

摘要

A porous ribbed substrate for a fuel cell electrode is herein disclosed which has a ribbed layer on one side and a non-ribbed layer with a bulk density larger than the bulk density of the ribbed layer. The fuel cell electrode substrate has a porosity of 50-80% and good mechanical strength such as a bending strength of not less than 50 kg/cm2. A fuel cell prepared from the electrode substrate has excellent properties.
