Membrane-electrode unit for a high temperature fuel cell for e.g. traction systems of vehicles comprises gas diffusion electrodes with electrolytes

摘要

Membrane-electrode unit (14) comprises gas diffusion electrodes (18a, 18b) with electrolytes (28). Independent claims are also included for the following: (1) Method for the production of a membrane-electrode unit; and (2) Fuel cell with the membrane-electrode unit. Preferred Features: The catalyst layers (20a, 20b) of the gas diffusion electrodes contain at least 1.0 mmol electrolyte. The catalyst layers contain a polymer binder component with a high affinity to the electrolytes.
