In high-temperature fuel cells, for example the solid oxide fuel cell (SOFC) and molten carbonate fuel cell (MCFC), anode waste gases containing hydrogen and carbon dioxide are separated from the waste gas stream by means of, e.g., a scrubbing step and/or an adsorption system, and the thus-obtained hydrogen is recycled to the anode. For the operation of an MCFC system, the carbon dioxide separated from the anode waste gas is reused by being admixed to the oxygen stream entering the cathode.
Apparatus comprising high temperature fuel cell means containing an anode chamber, a cathode chamber, and a molten carbonate electrolyte; CO2 separation means comprising scrubbing means in communication with said anode chamber; pressure increasing means for increasing the pressure of a separated component stream from said scrubbing means; recycle conduit means in communication with said pressure increasing means and said cathode chamber so as to permit gas from said pressure increasing means to be recycled to said cathode chamber; hydrogen separation mea...
