Fuel cell stack for a motor vehicle has fuel cells each with an electrolyte unit, two electrodes and separator units with first, second and third fluid channels

A fuel cell stack (FCS) (10) has a layered structure of several single fuel cells (20,30,40) and is enclosed by end plates (50,60). Two contact elements (70,80) take current away. For each fuel gas and a coolant the FCS has a collector channel impinged with fuel gas via connector links (90,100) and...

Zusammenfassung:A fuel cell stack (FCS) (10) has a layered structure of several single fuel cells (20,30,40) and is enclosed by end plates (50,60). Two contact elements (70,80) take current away. For each fuel gas and a coolant the FCS has a collector channel impinged with fuel gas via connector links (90,100) and with a coolant via a connector link (110). Die Erfindung betrifft einen Brennstoffzellenstapel, insbesondere für ein Kraftfahrzeug, bestehend aus Brennstoffzellen mit je einer Elektrolyteinheit, zwei Elektroden und aus Separatoreinheiten mit ersten, zweiten und dritten Fluidkanälen.
