Claim 10:
11. A method for operating a fuel cell system having a plurality of injection devices for injecting raw fuel, comprising:
controlling an operation of:
a first injection device connected to a storage unit that stores the raw fuel and configured to receive the raw fuel from the storage unit, and
a second injection device connected to the storage unit, the second injection device being located upstream of the first injection device on a fuel flow passage from the storage unit of the raw fuel to the first injection device and configured to receive the raw fuel from the fuel flow passage;

during a system high temperature period where the fuel cell system is in a high temperature state, stopping the second injection device while distributing the raw fuel from the first injection device to supply fuel to a fuel cell; and
during a system low temperature period where the fuel cell system is in a low temperature state, stopping the first injection device while distributing the raw fuel from the second injection device to perform a warmup of the system.
