Fuel cell generator containing a gas sealing means

Patent ·
OSTI ID:6780034

This patent describes a high temperature solid electrolyte electrochemical generator comprising: (A) an exterior housing; (B) a gas permeable thermal insulation layer disposed next to and within the exterior housing; (C) an interior volume defined by the thermal insulation. The volume contains a fuel gas inlet generating chamber and a combustion product chamber contains combustion product outlet means, with a gas permeable partition dividing the fuel gas inlet generating chamber and combustion product chamber; (D) electrochemical cells, having solid electrolyte, disposed within the generating chamber; (E) means for supplying fuel gas and oxidant gas to the electrochemical cells for reaction in the generating chamber, so that reacted fuel gas passes through the gas permeable partition; and (F) seal means disposed through the thermal insulation and extending from the exterior housing to the gas permeable partition, so that reacted fuel gas cannot pass from the generating chamber into the combustion product chamber through the thermal insulation, but must pass through the gas permeable partition into the combustion product chamber.
