摘要： A fuel cell system includes: a polymer electrolyte fuel cell; a resistance sensor that detects the internal resistance of the fuel cell; a dew point sensor that detects the dew point of anode off gas from the fuel cell; and a controller that executes an electrolyte membrane hydration control according to the relationship between the internal resistance and the dew point. According to this configuration, it is possible to define, based on the relationship between the internal resistance and the dew point, the conditions under which the decreased power generation performance of the cell may be quickly recovered.

摘要： A fuel cell system includes fuel cell stacks electrically connected in parallel and supplying a gross current to a load. A controller determines the gross load current, and produces a desired current through the load by adjusting, based on the gross load current, at least one parameter affecting at least one of the inputs to and outputs from the system. This system allows a stack design and its voltage output to be kept constant while stacks are added for increased power.

摘要： Methanol forms the fuel of the fuel cells and it is supplied to the system. An anode fluid including waste gases, such as carbon dioxide or the like, have to be led away after combustion. The carbon dioxide, which develops on the anode, is separated while it is hot from the anode fluid after leaving the anode of the fuel cell stack. The vaporous fuel separated together with the carbon dioxide is depleted in a counter-current flow using cold water. The cold water is recovered in the condenser of the cathode waste gas, and the resulting warmer water is admixed to the anode liquid. In the installation, a cooler with a CO2 trap arranged downstream is provided at least for the anode fluid, and a unit for carrying out rectification provided with which fuel contained there is separated and returned into the fuel circuit.

摘要： A method for shutting down a fuel cell system (2) having at least one fuel cell (3), which fuel cell comprises an anode chamber (10) and a cathode chamber (6), wherein after the shut-down hydrogen remains in the anode chamber (10) of the fuel cell (3) in order to prevent carbon corrosion and to ensure a hydrogen protection time. The invention is characterized in that when the hydrogen in the anode chamber (10) is largely used up directly or after a specified number of subsequent meterings of hydrogen at least into the anode chamber (10), the hydrogen protection time is actively terminated by air being actively admitted into the cathode chamber (6), the fuel cell (3) being actively cooled before air is actively admitted into the cathode chamber (6).
