Production of electrical energy from hydrogen-rich crude gas

摘要

The hydrogen-rich crude gas produced is fed to a membrane filter to remove the content of carbon dioxide, a large part of the carbon monoxide and other impurities and divided into a filter waste gas stream and pre-purified hydrogen gas stream. The pre-purified hydrogen gas stream is then subjected to catalytic oxidation of the remaining carbon monoxide and fed to the fuel cell. Electrical energy is produced by: (a) producing a hydrogen-rich and amounts of raw gas containing carbon dioxide and carbon monoxide by catalytically converting liquid and/or gaseous fuels; (b) removing impurities from the raw gas to form a hydrogen gas stream suitable for a fuel cell; and (c) introducing the hydrogen gas stream into the anode chambers of a fuel cell. The hydrogen-rich crude gas produced is fed to a membrane filter to remove the content of carbon dioxide, a large part of the carbon monoxide and other impurities and divided into a filter waste gas stream and pre-purified hydrogen gas stream. The pre-purified hydrogen gas stream is then subjected to catalytic oxidation of the remaining carbon monoxide and fed to the fuel cell. An Independent claim is also claimed for an apparatus for carrying out the production of electrical energy comprising a device (1) for catalytically converting fuels into hydrogen-rich crude gas, a purifier for removing impurities from the crude gas, and a fuel cell (4) for producing electrical energy from the purified hydrogen-rich gas. The purifier is a membrane filter (2) with a catalytic oxidation device (3) connected to the anode chamber of the fuel cell (4).
