摘要： The invention relates to a fuel cell system, comprising a plurality of fuel cells combined to form a fuel cell stack. The fuel cell system is characterized in that at least one fuel cell is a redox flow fuel cell having an electrode assembly, which electrode assembly has a proton-permeable separator, which separator is arranged between an anode region and a cathode region. The redox flow fuel cell has a regenerator spatially separated from the electrode assembly, and a water-forming reaction of the redox flow fuel cell occurs in the regenerator. The redox flow fuel cell also comprises at least one oxidation-fluid conveying unit for feeding oxidation fluid into the regenerator in order to perform the water-forming reaction in the regenerator of the redox flow fuel cell. The redox flow fuel cell also comprises a pumping circuit, comprising a pumping device and a pumping line, for transporting an electrochemical storage system through the cathode region or the anode region of the redox flow fuel cell and through the regenerator. The electrochemical storage system contains active redox molecules and is designed to receive and release electrons. The fuel cell system also comprises a control device, which is designed to adjust an available electrical and/or thermal power of the fuel cell system by changing a redox state of the electrochemical storage system.

摘要： The invention relates to an operating method for a fuel cell system with a radiator structure which is flowed through by ambient air and a fuel cell stack, at least part of the outgoing air flow of which can be guided onto the radiator structure in such a way that, at the radiator structure, said guided outgoing air flow causes an increase in the mass flow of the ambient air through the radiator structure according to the jet pump principle, and wherein at least part of the outgoing air flow of the fuel cell stack can be guided through a gas expansion machine and the division of the energy which is contained in the outgoing air flow and can be recovered in the gas expansion machine and/or at the radiator structure according to the jet pump principle is changed by an electronic control unit in a manner which is adapted to boundary conditions. Said division is set and changed, in particular, using the temperature of the medium to be cooled in the radiator structure and the required electrical power of the fuel cell stack, by the pressure drop in the gas expansion machine being set by targeted setting of the flow conditions prevailing therein and/or the magnitude of the outgoing air flow which is guided through the gas expansion machine being set by means of a controllable bypass of said gas expansion machine.

摘要： The present invention relates to a fuel cell system having a plurality of individual fuel cells which are combined to a stack, each of said individual fuel cells consisting of a substantially planar membrane-electrode unit, two gas diffusion layers in the form of a fiber structure and of a bipolar plate, which establishes the electrical connection to the adjacent individual fuel cell that is located above or below, wherein the gas diffusion layers adjoin the larger surfaces of the membrane electrode unit, which are located opposite of one another. The bipolar plate according to the invention comprises an active region surrounded by an edge region. In order to create a fuel cell system of the above-mentioned type, which is particularly thin, has no disadvantages in terms of weight, volume and power and moreover can be achieved in a cost-effective manner, it is proposed according to the invention that the bipolar plates in the active region have a completely flat design so that the gas-carrying region is formed exclusively by the gas diffusion layers, what amounts to at least 60% of the height of an individual fuel cell.
