Apparatus and method for heating subterranean formations using fuel cells
InactiveUS6684948B1Eliminate needAvoid inefficiencyFuel cell heat exchangeFuel cells groupingElectricityFuel cells
A fuel cell based subterranean heater for mineral extraction, in situ decontamination, or other applications. The fuel cells are preferably stacked within a casing which is then inserted into a hole bored, or otherwise formed, into the formation to be heated. Conduits within the casing, and preferably formed by adjacent, aligned holes formed through the plates of the individual fuel cells supply fuel and air and extract exhaust gases. An optional manifold is used to span the overburden without applying heat to it directly. The manifold may also function as a heat exchanger between incoming and exhaust gases. Preferably the fuel cell is fueled by gases produced by the formation and also generates electricity which is available for use or export.

In a co-generated power supply system for performing dispersed power supply to a load, a wind turbine generator, a solar cell and a fuel cell whose rated voltages are made equal to a rated voltage of a storage battery are used as DC power sources. These DC power sources, a commercial AC power source and the load are connected to each other via a bi-directional electronic transformer. Thus, the co-generated power supply system, in which the electric power of a natural energy system having many fluctuation factors is combined with stable electric power such as a load leveling battery or a fuel cell, allows the stable electric power to be supplied to the load via the electronic transformer commonly, thereby reducing the cost and enhancing the performance of the entire system.
