Abstract
A fuel cell is cooled by circulating a stream through the cell, the stream containing a reactive material which undergoes an endothermic reaction within the fuel cell, absorbing waste heat. The material, upon leaving the fuel cell, passes through a regenerative heat exchanger where heat is removed. The reacted material then undergoes an exothermic reaction, releasing the waste heat absorbed within the fuel cell. After the exothermic reaction, the material is returned to the fuel cell to repeat the cooling cycle. Utilizing a reactive cooling system based on the heat of reaction as a means for removing waste heat allows reducing the amount of gases supplied to the fuel cell, thus reducing the size of the internal gas passages and consequently, the overall size of the fuel cell while maintaining a high power output.
