Abstract
Official abstract text for this publication.
A method for preparing a fuel cell system in a vehicle for starting, for which purpose a starting preparation routine is carried out after the vehicle has been shut down depending on a temperature limit value. In the method, in the event that the fuel cell had not reached its normal operating temperature during the previous operation and a temperature falls below the predetermined temperature limit value, the fuel cell system is operated until it has reached its normal operating temperature and after which the starting preparation routine is subsequently carried out.
First claim
Opening claim text (preview).
1 .- 5 . (canceled) 6 . A method for preparing a fuel cell system in a vehicle for starting, comprising the steps of: when the fuel cell system did not reach a normal operating temperature of the fuel cell system during a previous operation and a current temperature falls below a predetermined temperature limit value, operating the fuel cell system until the fuel cell system reaches the normal operating temperature and subsequently performing a starting preparation routine. 7 . The method according to claim 6 , wherein the starting preparation routine is performed only after the fuel cell system has cooled down to the predetermined temperature limit value after reaching the normal operating temperature. 8 . The method according to claim 6 , wherein the normal operating temperature is 60° C. to 70° C. 9 . The method according to claim 6 , wherein the predetermined temperature limit value is 0° C. to 10° C. 10 . The method according to claim 6 , wherein the current temperature is measured in an interior of the fuel cell system. 11 . The method according to claim 10 , wherein the current temperature is measured in a region of a fuel cell of the fuel cell system and/or in a region of a coolant for the fuel cell.
