  • METHOD FOR DETECTING A CRITICAL CONCENTRATION OF HYDROGEN
    Publication number: 20150228989
    Abstract: A method for detecting a critical concentration of hydrogen in the exhaust gas of a fuel cell system (1), in which exhaust gas from an anode chamber (4) of a fuel cell (3) is post-combusted by means of a burner (17). The temperature of the combustion exhaust gases is detected, the temperature being compared to a predetermined limit value. In the comparison, a critical concentration of hydrogen is assumed if the temperature of the combustion exhaust gases is above the limit value.

  • Charging Device for a Fuel Cell, in Particular of a Motor Vehicle
    Publication number: 20140370412
    Abstract: A charging device for a fuel cell includes a turbine having a housing part with a receiving chamber in which a turbine wheel of the turbine is received so as to be rotatable relative to the housing part about an axis of rotation. The turbine wheel includes impeller vanes via which a medium, in particular a gaseous waste gas of the fuel cell, can flow against the turbine wheel in an inlet region, and which are curved forwards at least in the inlet region.

  • Fuel cell system having at least one fuel cell
    Patent number: 8685582
    Abstract: A fuel cell system includes at least one fuel cell and at least one air conveyor that conveys a process air flow to the fuel cell. At least one heat exchanger is also provided, through which the process air flow flows after the air conveyor and through which a cooling medium flow flows. A region with catalytically active material is arranged in the flow direction of the process air flow before or in the region of the heat exchanger. In addition a fuel can be fed to the region with the catalytically active material.

  • Device for Providing Hot Exhaust Gases
    Publication number: 20130029236
    Abstract: A device used to provide hot exhaust gases for driving a turbine. The device includes a burner, the combustion zone of which is directly mounted on or integrated into the gas inlet (turbine housing) of the turbine. The burner is supplied with at least one combustible gas or gas mixture. The combustion zone includes a porous material with a large specific surface area.
