    摘要: In a device for providing heating energy to a gas-generating system by means of essentially complete catalytic combustion of a fuel on a suitable catalyst material, heat energy is transferred directly or by means of a heat-conducting medium from the catalytic burner to the gas-generating system. To improve the starting behavior and the exhaust emissions, the device comprises three components that are at least temporarily traversed by fuel, with a cold-start component having an electrical heating device. The central component is preferably designed as a filter press with an integrated heat exchanger. A third, unheated, stage is also provided for residual gas combustion.

    摘要: A process and an apparatus control output of an air-breathing fuel cell system which consists of an air supply line, a fuel cell, an air exhaust line, and a separate gas supply system for hydrogen gas. To control the fuel cell output, an adjustable rotary speed compressor is located in the air supply line and a variable absorption capacity expander is located in the air exhaust line. The compressor, the expander, and an additional electric motor are positioned on a common shaft. The expander converts the pressure energy contained in the exhaust air into mechanical energy and delivers that energy via the common shaft to the compressor. The air volume flow is controlled by the compressor rotary speed and adjusted to a preset value. A preset working pressure is established in the fuel cell system by adjusting the absorption capacity of the expander.
