Model-Based Design of Energy Efficient Palladium Membrane Water Gas Shift Fuel Processors for PEM Fuel Cell Power Plants

An integrated, palladium alloy membrane Water-Gas Shift (WGS) reactor can significantly reduce the size, cost and complexity of a fuel processor for a Polymer Electrolyte Membrane fuel cell power system. Physics-based system modeling that accounts for component performance under transient conditions is essential to derive the full benefit from this technology. Modeling elucidates system designs and operating philosophies that maximize system efficiency and performance. This advanced WGS membrane reactor fuel processor is enabled by high activity noble metal alloy/ceria-based WGS catalysts [1, 2] and porous metal tube supported palladium alloy membranes such as those investigated by Ma and co-workers [3–6].
