A single cell for a fuel cell stack is provided, having a membrane electrode assembly arranged in an active region, being associated with at least one single plate, which is formed with a flow field to supply an operating medium to the active region of the membrane electrode assembly, which is fluidically connected to a media port present on the side away from the active region. Lateral with respect to the membrane electrode assembly there is a lamella at least partly covering the flow cross section of the media port, which is formed to be elastically bendable by the force of a reaction medium flowing axially through the media port in order to change the useful flow cross section of the media port. A fuel cell stack having a plurality of such single cells is also provided.

Single cell and fuel cell stack with elastic structures for equal distribution of operating media

A fuel cell assembly has a first gas diffusion layer on the cathode side, a second gas diffusion layer on the anode side, a membrane located between the first gas diffusion layer and the second gas diffusion layer, a first electrode located between the membrane and the first gas diffusion layer and a second electrode located between the membrane and the second gas diffusion layer, and a frame with a recess, held by means of an adhesive layer against the gas diffusion layers. One of the electrodes is arranged on one of the gas diffusion layers to form a gas diffusion electrode, while the other of the electrodes is arranged on the side of the membrane opposite the gas diffusion electrode to form a one-sided membrane electrode arrangement. The electrode-free side of the membrane is bound to the frame directly by the adhesive layer. A fuel cell device and a motor vehicle having a fuel cell device are also provided.

A method for producing a membrane electrode assembly for a fuel cell includes providing a first component of the membrane electrode assembly as part of a continuous material web which passes through a plurality of processing stations and connecting a second component of the membrane electrode assembly to the first component by a firmly bonded connection.
