Abstract

A direct-electrochemical-oxidation fuel cell and method for generating electrical energy from a solid-state organic fuel. The fuel cell includes a cathode provided with an electrochemical-reduction catalyst that promotes formation of oxygen ions from an oxygen containing source at the cathode, an anode provided with an electrochemical-oxidation catalyst that promotes direct electrochemical oxidation of the solid-state organic fuel in the presence of the oxygen ions to produce electrical energy, and a solid-oxide electrolyte disposed to transmit the oxygen ions from the cathode to the anode. The electrochemical oxidation catalyst can optionally include a sulfur resistant material.

Description

[0001] related application

[0001] This application claims the benefit of US Provisional Application No. 60 / 520,155, filed November 14, 2003; and US Provisional Application No. 60 / 558,856, filed April 2, 2004. field of invention

[0002] The present invention relates generally to the generation of electrical power from solid fuels, and more particularly to solid-oxide fuel cells for generating electrical power from solid organic fuels based on direct electrochemical oxidation of the solid organic fuels. Background of the invention

[0003] Conventional solid-oxide fuel cells utilize an electrolyte placed between an anode and a cathode to facilitate the transfer of ions between them. Traditionally, solid fossil fuels, such as coal, have had to be gasified and reformed before being introduced into solid-oxide fuel cells to generate electricity. Despite the additional processing steps required, using such solid-state fuel cells to generate electricity remains an attractive op...
