Abstract
A fuel cell corrugated current collector having successive spaced rows of corrugations, with the corrugations in a given row establishing successive peak and valley regions along the given row and the spaced rows of corrugations being adapted so that corresponding peak regions from row-to-row establish through passages for receiving and supporting solid catalyst elements. The spaced rows of corrugations are such that there is a given pitch between successive peak regions. The corrugations in the rows are also such that corresponding peak regions from row-to-row have a finite off-set which is less than 50 percent of the pitch. This establishes a plurality of through passages in the current collector each extending from row-to-row for receiving and supporting the solid catalyst elements. Also, the off-set is based on the catalyst dimensions and is set such that the corrugations engage the catalyst elements.
