FUEL CELL SYSTEM AND METHOD OF STARTING A FUEL CELL SYSTEM IN A COLD START PHASE

摘要

The invention relates to a fuel cell system with at least one fuel cell (2), whose anode side (4) is connected to a fuel branch (6), via which fuel may be supplied to the anode side (4) by means of a metering unit (8) arranged in the fuel branch (6), wherein a cold start branch (18) branches off from the fuel branch (6) upstream of the metering unit (8), which cold start branch (18) leads into the fuel branch (6) downstream of the metering unit (8) and which is designed to meter fuel into the fuel branch (6) in a cold start phase of the fuel cell (2) in the event of the passage cross section of the metering unit (8) being at least reduced due to liquid freeze out. The invention also relates to a method of starting a fuel cell system in a cold start phase.
