Hydrogen Supply System for Small PEM Fuel Cell Stacks

摘要

This program was to determine how to employ thermolysis of chemical hydrides to produce low cost hydrogen for Soldier Power System (SPS) type fuel cells. Originally, the program was directed at the Digital Reactor concept. Early in the program, we determined that the digital reactor could not be made safe, light weight, or at low cost. We attempted to find an alternative to the digital reactor which, while still employing Beckert Dengel thermoloysis chemistry, could be made safe, light weight, and inexpensive. We failed in that attempt as well. This report documents the fundamental problems to be overcome in developing a chemical hydride based hydrogen generator.
