ABSTRACT:
A power supply for providing electricity to one or more electrical circuits located downhole in a well comprises a fuel cell adapted to be disposed in the well with the electrical circuit(s). In addition to generating electricity, the fuel cell produces a byproduct liquid, such as water, which can be expelled from the power supply into the well despite substantial pressure, such as hydrostatic pressure, in the well. The fuel cell also generates heat which can be dissipated into the well through the wall of a housing of the power supply. The byproduct liquid can be circulated through the fuel cell to accomplish or assist in this heat dissipation.
