FUEL CELL STACK WITH A FLOW FIELD CONFIGURATION
Abstract:
A method of manufacturing a plate for a fuel cell includes the steps of providing flow channels in a fuel cell plate. Multiple fuel cell plates are joined into a cell stack assembly. A blocking plate is affixed to the fuel cell plate and at least partially obstructs the flow channels. The blocking plate is affixed to the fuel cell plate after the plates have been arranged into the cell stack assembly. The resulting fuel cell provides a fuel cell plate having a perimeter with an edge. The fuel cell plate includes flow channels extending to the edge. The blocking plate is affixed to the fuel cell plate at the edge to at least partially block the flow channel. In this manner, an inexpensive fuel cell plate may be used, and the blocking plate can be configured to create terminated flow channels, which may be used to provide an interdigitated flow field.
