System and method for the removal of hydrogen from fuel cell waste gas

The waste gases gas and air, are supplied to a catalytic burner (3). If desired, a third gas including fuel, and/or water are supplied to the catalytic burner. The hydrogen content is oxidized catalytically, producing a waste gas from the burner. Hydrogen content and temperature of the burner waste gas are monitored. On departure from a given value, control is applied as required and/or the temperature of the catalytic burner is monitored and so controlled, that a desired temperature range is maintained. Catalytic burner temperature is controlled by varying supply of one of the feeds cited above, in accordance with temperature. An independent claim is included for the corresponding vehicle burner system.
