Abstract
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.
Claims26
A fuel cell plate, comprising;
- a substrate of electrically conductive material;
- and
- a first outer layer of corrosion-resistant material bonded to a first portion of the substrate,
- wherein the fuel cell plate comprising the electrically conductive material with the first outer layer of the corrosion-resistant material is lighter and more corrosion-resistant than a fuel cell plate composed of a single material.

A method for manufacturing a fuel cell plate, comprising:
- arranging a first outer layer of corrosion-resistant material over a first portion of a substrate of electrically conductive material;
- and
- bonding the first outer layer to the substrate to produce the fuel cell plate, wherein the fuel cell plate comprising the electrically conductive material with the first outer layer of the corrosion-resistant material is lighter and more corrosion-resistant than a fuel cell plate composed of a single material.
A fuel cell stack, comprising:
- a set of fuel cell plates coupled together, wherein each of the fuel cell plates comprises:
- a substrate of electrically conductive material;
- and
- a first outer layer of corrosion-resistant material bonded to a first portion of the substrate,
- wherein the fuel cell plate comprising the electrically conductive material with the first outer layer of the corrosion-resistant material is lighter and more corrosion-resistant than a single material.
2 more elements
A portable electronic device, comprising:
