Reduced-weight fuel cell plate with corrosion resistant coating

摘要

The disclosed embodiments provide a fuel cell plate. The fuel cell plate includes a substrate of electrically conductive material and a first outer layer of corrosion-resistant material bonded to a first portion of the substrate. To reduce the weight of the fuel cell plate, the electrically conductive material and the corrosion-resistant material are selected to be as light as practicable.

主权项

1. A fuel cell plate, comprising:
a substrate of electrically conductive material; a first outer layer formed from a first outer layer material different from said electrically conductive material and adjacent a first portion of the substrate, the electrically conductive material having a lower density than the first outer layer material; a second outer layer formed from a solderable material different from said first outer layer material and adjacent a second portion of the substrate; and a first coating of corrosion-resistant material bonded to at least a portion of an outer surface of the first outer layer; and a second coating of solderable, corrosion-resistant material different from said first coating of corrosion-resistant material, said second coating bonded to at least a portion of an outer surface of the second outer layer.
