Abstract:
A combined component for a fuel cell system, comprising:an exhaust gas catalyzer for afterburning anode exhaust gases from the fuel cell system; and an evaporator for evaporating at least one educt to be fed to the fuel cell system; wherein the exhaust gas catalyzer includes a casing with a casing cover and a casing bottom, a gas inlet and a gas outlet connection disposed on the casing cover and on the casing bottom respectively, a gas-permeable inner tube arranged coaxially with a long axis of the casing affixed to the casing cover, and a gas-permeable outer tube disposed coaxially with the long axis of the casing joined to the casing cover, a catalyst material in an area between the inner and the outer tube for the catalytic oxidation of the anode exhaust gas, the outer tube having a radius (rA) greater than the radius (rI) of the inner tube, yet smaller than the radius (rG) of the casing; and the evaporator is disposed between the inner tube and the outer tube, and includes at least one inlet tube, an outlet tube, and at least one set of educt flow tubes connected between said at least one inlet and said outlet tube and passing around the inner tube.
