Abstract
A system for fabricating a fuel cell component in which a deposition mechanism deposits loading material particles onto the fuel cell component and an actuation mechanism actuates the deposition mechanism. A unit provides a tape fixing agent to the fuel cell component and loaded material particles so as to retain the particles on the fuel cell component. Other fuel components are retained to the fuel cell component also using a tape fixing agent.
Claims19
A method of fabricating a fuel cell component for use with or as part of a fuel cell in a fuel cell stack, the fuel cell component comprising a corrugated current collector and the method comprising:
- depositing loading material onto the corrugated current collector in predefined areas defined by legs of corrugations of the corrugated current collector, the loading material comprising one of an extruded catalyst and catalyst pellets;
- maintaining positioning of the loading material relative to the predefined areas of the corrugated current collector by applying a tape fixing agent to the corrugated current collector and sealing the loading material against respective legs of the corrugations of the corrugated current collector, wherein the tape fixing agent is an adhesive tape.
An assembly for use with or as part of a fuel cell stack, the assembly comprising:
- a fuel cell component comprising a corrugated current collector;
- a loading material deposited in predefined areas defined by legs of corrugations of the corrugated current collector, the loading material comprising one of an extruded catalyst and catalyst pellets;
- and
- a tape fixing agent comprising an adhesive tape applied to the corrugated current collector, wherein the tape fixing agent maintains positioning of the loading material relative to the predefined areas of the current collector and seals the loading material against respective legs of the corrugations of the corrugated current collector.
