HYDROGEN GENERATION FOR FUEL CELLS.
Abstract
Test operations were continued with portable hydrogen generators utilizing ammonia as the fuel. A final prototype unit was built and successfully operated. Performance checks demonstrated that the unit could produce the design requirement of 4 SCFH of hydrogen within thirty minutes from a cold start with an igniter coil. Testing has indicated that 0.27 lbs. of hydrogen can be produced over a 12-hour period from approximately 2.5 lbs. of ammonia with a corresponding thermal efficiency of almost 70%. This completely self-sustaining unit utilizes residual hydrogen in the fuel gas to supply the process energy requirements and the waste stack gas to provide the heat of vaporization to the ammonia container to maintain a vapor pressure sufficient to operate the generator. Investigations on organic fuel have shown that it is possible to steam reform methanol at an equimolar water ratio and obtain conversion levels and hydrogen yields sufficient to operate a generator on a self-sustaining basis.
