Abstract
An apparatus for use in a wellbore includes a downhole tool, a fuel cell, a pressure applicator, and a desiccant. The wellbore has a wellbore fluid at hydrostatic pressure. The downhole tool is conveyed into the wellbore with a conveyance device. The fuel cell is associated with the downhole tool and receives a flow of an oxidant and a flow of hydrogen. The pressure applicator applies at least a portion of the hydrostatic pressure of the wellbore fluid to the fuel cell to increase a pressure applied to the fuel cell. The desiccant receives a fluid byproduct produced by the fuel cell.
