A fuel cell stack is disclosed. In one embodiment, the fuel cell stack includes a main body that is constructed with an assembly of a plurality of generators, and at least one heat pipe that is disposed in the main body to provide heat to the generators corresponding to heat-generating temperature differences according to positions of the generators.

Fuel cell stack

A fuel cell system is disclosed. In one embodiment, the fuel cell system includes: i) a fuel tank that contains a fuel in at least a partially liquefied state, ii) a heat-generating unit that generates heat, iii) a heat-transfer unit that is connected between the heat-generating unit and the fuel tank to transport the heat to the fuel tank, and iv) a temperature-regulating unit that regulates a temperature of the fuel tank.
