<p>A method of operating a fuel cell (101, 102, 103) comprising at least one (5) electrolyte based element (103). The method comprises the steps of locating the fuel cell in a downhole environment and whilst the fuel cell is in the downhole environment suppressing at least one of boiling and evaporation of electrolyte in the element by subjecting the element to a pressure in excess of atmospheric pressure. The fuel cell (101, 102, 103) is disposed in a pressure containment (10) vessel (3) which is pressurised to say 3 to 6 bar.</p> |
