FUEL CELL ANODE FLOW FIELD DESIGN CONFIGURATIONS FOR ACHIEVING INCREASED FUEL UTILIZATION

摘要

An anode of a fuel cell has an anoe current collector defining an inlet configured to receive fuel gas and an outlet configured to output the fuel gas, a barrier that divides an active area of the anode current collector into a first area and a second area, and a flow passage configured to allow a flow of fuel gas from the inlet through the first area and the second area to the outlet. An obstacle is located in the flow passage in an inactive area of the anode current collector and is configured to change a flow direction of the fuel gas in the flow passage from the first area to the second area to achieve intra-cell mixing of the fuel gas.
