Zero Emission Fuel System for Use with a Fuel Cell

Abstract

A self-contained fuel system for use with a high temperature fuel cell is described to address containment of carbon dioxide evolution. The system utilizes a slurry containing calcium carbide and calcium hydride that is pumped into a water reservoir. The resulting hydrolysis reaction generates acetylene, hydrogen and water-soluble calcium hydroxide. The acetylene and hydrogen are catalytically converted to synthesis gas, which is used by a fuel cell to generate electricity. Carbon dioxide exhaust from the fuel cell is reacted with calcium hydroxide to form a storable solid, calcium carbonate.
