Abstract
A flow board suited for fuel cell applications. The flow board includes a body substrate formed by injection molding methods, which is resistive to methanol or chemical corrosion and has superior mechanical properties. The flow board further includes a wave-shaped reaction zone having thereon a plurality of independent fuel channels. The body substrate and the wave-shaped reaction zone may be monolithic. Alternatively, a punched electrode plate affixed on the reaction zone may define the plurality of independent fuel channels.
Claims5
A method of manufacturing a wave-shaped current collector of a fuel cell, comprising:
- providing an anti-corrosion and anti-oxidation charge-collecting layer;
- covering a first side of said charge-collecting layer with a masking layer;
- plating a conductive layer on a second side of said charge-collecting layer;
- forming a photosensitive dry film on said conductive layer, wherein said photosensitive dry film defines a pattern of said current collector;
- etching away said conductive layer that is not covered with said photosensitive dry film;
- removing said photosensitive dry film and said masking layer;
- adhering a protection film on said second side of said charge-collecting layer to isolate said conductive layer;
- performing a cutting process to form a current collector;
- and
- stamping said current collector to form a wave-shaped current collector, thereby defining a plurality of flow channels thereon.
