1. A fuel cell system comprising:
a fuel cell;
a fuel storage unit configured to store raw fuel;
a fuel flow passage connected to the fuel storage unit, the fuel passage comprising a fuel rail;
a first injection device mounted on the fuel rail at a first location and configured to receive the raw fuel from the fuel rail and to supply fuel to the fuel cell;
a second injection device mounted on the fuel rail at a second location upstream of the first location and configured to receive the raw fuel from the fuel rail; and
a controller programmed to control the first injection device and the second injection device such that:
the first and second injection devices switch a flow of the raw fuel from the fuel storage unit between a first flow passage via the first injection device and a second flow passage via the second injection device, and
the second injection device operates less frequently than the first injection device during operation of the fuel cell system.
