ABSTRACT:
A fuel cell assembly including a number of fuel cells (12) arranged in a stack (10). Each fuel cell contains an anode (1), a cathode (2) and a porous electrolyte matrix (3) arranged therebetween. An electrolyte reservoir (11), which compensates the electrolyte losses from the fuel cells (12) is provided at the end, or in the vicinity of the end of the fuel cell stack (10). The electrolyte is transported to the individual fuel cells (12) by electrical forces within the fuel cell stack (10). The electrolyte reservoir (11) is configured as a supporting structure which forms hollow chambers that contain porous bodies for absorbing the electrolyte in their pores.
