HYDROGEN GENERATION FOR FUEL CELLS

Abstract

Test operations were performed with portable hydrogen generators utilizing ammonia as the fuel. Continued investigations have shown that the design requirement of 4 SCFH of hydrogen can be produced utilizing residual hydrogen to supply the process energy requirements. Re peated start ups and shutdowns have been accomplished. It is projected that a complete assembly incorporating a slightly modified version of these generators will meet the over-all volume and weight specifications. Tests con firmed that the waste stack gas could be utilized to provide the heat of vaporization to the ammonia container to maintain the ammonia vapor at a pressure sufficient to operate the generator. Refinement of the heat exchanger and controls still has to be engineered. With a view to equipment simplification through elimination of a second feed stream suitable mixtures of water and JP-4 were emulsified by simple shaking with an emulsifier.
