Hydrogen Supply System for Small Proton Exchange Membrane (PEM) Fuel Cell Stacks

1. A conceptual baseline design of a hydrogen supply system with a on/off capability will be prepared for delivering hydrogen in increments of up to 10g/hour with a total capacity of 120g hydrogen. This baseline design will be based upon a solid state hydrogen reactant mixture with a yield of 8% by reactant weight which has been previously qualified for military use. 2. Solid hydrogen reactant mixtures with theoretical yields of up to 20% will be evaluated and tested for thermal stability, safety, and performance. 3. The baseline hydrogen supply system will be upgraded for incorporation of a higher yielding hydrogen reactant mixture, assuming a suitable replacement is emerging. The design will demonstrate what yield per system weight is achievable with a solid state hydrogen generating reactant system and provide a concept for phase II development.
