SINGLE CELL AND FUEL CELL STACK WITH ELASTIC STRUCTURES FOR EQUAL DISTRIBUTION OF OPERATING MEDIA
DRIVE
August 17, 2023
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.
