Abstract
A method for making a component of a fuel cell utilizes a rotary die forming station for shaping a web of material into a configuration corresponding to the component. The component may comprise an exchanger plate. Also disclosed is a method for fabricating a fuel cell assembly wherein a gasket is affixed between portions of two exchanger plates, and the affixation may be accomplished by rotary die forming. Also disclosed are fuel cells and fuel cell assemblies made by these methods.
Claims18
A method for making a component of a fuel cell, said method comprising the steps of:
- providing a web of a material;
- providing a rotary die forming station configured to shape said web of material into a configuration corresponding to said component;
- and
- feeding said web through said station;
- whereby said station configures said web into a shape corresponding to said component.
A method of making a fuel cell, said method comprising the steps of:
- providing a first exchanger plate;
- providing a second exchanger plate;
- providing a gasket;
- disposing said gasket on a portion of a face of said first plate;
- disposing said second plate in a spaced apart, superposed relationship with said first plate so that a face of said second plate contacts said gasket;
- and
- deforming at least one of said plates or said gasket so as to fixedly retain said gasket to at least one of said plates.
A fuel cell including at least one component which is fabricated in a rotary die forming process.
