摘要： A fuel cell arrangement with a membrane electrode assembly is provided which comprises a cathode, an anode and a membrane arranged between the cathode and the anode, with an active area essentially predetermined by the membrane electrode assembly, and with a sealing structure laterally assigned to the membrane electrode assembly. The sealing structure comprises a sealing tongue extending into or over an edge region outside the active area for axially covering in a gas-tight manner a media channel formed in an adjacent bipolar plate and located in the edge region. A unit cell for a fuel cell stack with such a fuel cell arrangement is also provided.

摘要： A fuel cell device is provided comprising a fuel cell stack, which is formed from a plurality of unit cells which are stacked one above the other in a stacking direction and which each have one or more media channels and a membrane electrode assembly, which comprises a cathode, an anode and a membrane arranged between the cathode and the anode, as well as comprising a media guide extending essentially in parallel to the stacking direction. The media guide can be or is connected to the fuel cell stack in such a way as to guide a medium essentially laterally to the stacking direction into or out of the media channels of the unit cells of the fuel cell stack.

摘要： A kit for a fuel cell stack comprises a first plurality of unit cells of the same design, which can be stacked on top of each other in a stacking direction and which each have one or more media channels and a membrane electrode assembly, the membrane electrode assembly comprising a cathode, an anode, and a membrane arranged between the cathode and the anode, a first media guide, which can be laterally connected to the first plurality of unit cells and runs parallel to the stacking direction, having a first usable flow cross section, in order to guide a medium into or out from the media channels of the unit cells of the first plurality of unit cells substantially laterally with respect to the stacking direction, a second plurality of unit cells of the same design, and a second media guide, which can be connected laterally to the two pluralities of unit cells stacked on top of one another and running parallel to the stacking direction, having a second usable flow cross section, different from the first usable flow cross section, in order to guide a medium into or out from the media channels of the unit cells of the two pluralities of unit cells substantially laterally to the stacking direction. A method for production of a fuel cell stack of a fuel cell device is also provided.

摘要： A fuel cell device comprises a fuel cell stack which is formed from a plurality of unit cells stacked one above the other in a stacking direction, each unit cell having one or more media channels and a membrane electrode assembly that comprises a cathode, an anode, and a membrane arranged between the cathode and the anode, and comprising a media duct running substantially parallel to the stacking direction. The media duct is connected or can be connected to the fuel cell stack to conduct a medium into or out of the media channels of the unit cells of the fuel cell stack substantially laterally to the stacking direction. The media duct is formed as a functional component or such a functional component is integrated therein, which is formed to pre-treat the medium before it enters the media channels or to post-treat the medium after it has exited the media channels.
