Title:
POLYMER ELECTROLYTE FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2010/073699
Kind Code:
A1
Abstract:
Gas discharged from a polymer electrolyte fuel cell which uses a liquid organic fuel contains unused fuel vapor or imperfectly oxidized substances of the same. A method for efficiently removing these organic substances is necessary. Provided is a polymer electrolyte fuel cell which is comprised of a solid polymer electrolyte film; electrodes connected to the opposed surfaces of the solid polymer electrolyte film; and passages through which a fuel or an oxidizing agent is supplied to the respective electrodes, and which uses a liquid organic compound as a fuel, characterized in that an organic gas component composed of unused fuel or imperfectly oxidized substances of the fuel contained in the exhaust gas of the fuel, and carbon dioxide are separated from a liquid component of the fuel; and a separator to which a part of the exhaust gas of the oxidizing agent which has passed through the polymer electrolyte fuel cell, and a catalytic reactor having a catalyst for oxidizing an organic gas component of gas introduced from the separator are provided. The exhaust gas of the fuel and the exhaust gas of the oxidizing agent are separately treated by catalysts, so that the organic compounds contained in the exhaust gas can be oxidized and removed.
