Title (EN) DOWNHOLE FUEL CELL WITH STEAM ADSORPTION AND PRESSURE COMPENSATION
(FR) PILE À COMBUSTIBLE DE FOND DE TROU AVEC ADSORPTION DE VAPEUR ET COMPENSATION DE PRESSION
Abstract:
(EN) A fuel cell for use in downhole applications stores steam created by the chemical reaction in a desiccant like Zeolite. The fuel cell also uses ambient hydrostatic pressure to increase cell voltage and power-density.
(FR) La présente invention concerne une pile à combustible destinée à être utilisée dans des applications de fond de trou et qui emmagasine la vapeur créée par la réaction chimique dans un dessiccatif tel que la zéolite. La pile à combustible peut également utiliser la pression hydrostatique ambiante pour faire augmenter la tension de la pile et sa densité de puissance.
