Abstract: An expansion and degassing container is in an expansion and degassing device for connecting to a circuit system for a circulating liquid. Because the amount of circulating liquid in the circuit system constantly changes during operation, liquid is withdrawn from the expansion and degassing container by way of a pressure holding pump, or supplied via a supply line, if needed. The supply line for supplying the refilling liquid is provided as a closed line, a system separator being arranged at the beginning region of the line and the end region thereof penetrating the container cover of the expansion and degassing container in a pressure-tight manner. The valve of the supply line is controlled according to the liquid level in the container. A pressure load cell, which additionally controls the valve according to the pressure, is present as a unit for decreasing an undesirable level of negative pressure.

Abstract: A high-temperature polymer electrolyte membrane fuel cell stack has at least two high-temperature polymer electrolyte membrane fuel cells (HT-PEFC), which comprise at least one means for determining the CO2 concentration of the cathode waste gas. A method for checking this fuel cell stack is thus possible, wherein at least the CO2 concentration of the cathode waste gas is determined. Optionally, the CO2 concentration of the oxidizing agent that is supplied can also be determined. The CO2 concentration is advantageously conducted in the region of individual cells or cell sections. This can be done, for example, by way of a displaceable lance in the cathode waste gas channel or a plurality of outlets (valves) in the cathode waste gas channel. If a threshold value defining the normal state of functional individual cells is exceeded, appropriate measures can be initiated, such as switching off the entire stack and optionally replacing cells or cell blocks.
