Fuel cell and method of cold start-up of such a fuel cell

摘要

The fuel cell has an electrolyte-electrode unit on which the cathode of the fuel cell is arranged on one side and the anode on the other side and flow modules for process gas and coolant for the fuel cell arranged above both electrodes. The flow module or modules arranged above the anode and/or cathode consists at least partly of a material that can form a hybrid whereby heat is given off. Independent claims are also included for the following: a fuel cell unit consisting of several fuel cells wired together and a method of cold starting an inventive device.
