A fuel cell system ( 10 ) is adapted for positioning within a well (W) dug into the ground. The subterranean fuel cell system ( 10 ) comprises a capsule ( 12 ) for insertion into the well (W) and for containing a fuel cell stack ( 14 ), fuel storage tank ( 16 ), and a BOP assembly ( 18 ). Cathode air enters the system ( 10 ) through an inlet pipe ( 24 ) and exits via an exhaust pipe ( 28 ). The remaining fluid circuitry (e.g., anode fluid circuit, cooling fluid circuit) can be located within the capsule ( 12 ) and/or below the ground level (G) whereby external plumbing, and the need for hoses, tubes, and connections, is minimized. The ground can function as a heat sink for absorbing system heat and as an insulator for preventing freezing of reactant and/or cooling water.
