초록 ▼

An arrangement for replenishing hydrogen consumed in a fuel cell device includes a reaction vessel that contains a quantity of a material that releases hydrogen on contact with water in a highly exothermic reaction. A hydrogen-containing gaseous medium is passed through the material quantity under conditions resulting in removal of heat from the material quantity by convection at a heat removal rate sufficient to maintain a temperature differential between an inlet portion and an outlet portion of the reaction vessel below a predetermined level. This includes recirculating a portion of the gaseous medium from the outlet portion to the inlet portion and cooling at least the recirculated portion. Water vapor is added to the recirculated gaseous medium portion at a rate commensurate with that at which hydrogen is being consumed in the fuel cell device for such added water vapor to exothermically react with the solid material, whereas the remainder of the gaseous medium is supplied from the outlet portion to the fuel cell device.

An arrangement for replenishing hydrogen consumed in a fuel cell device, comprising means for confining in an enclosed space having an inlet portion and an outlet portion, a gas-permeable bed of a solid material that releases hydrogen on contact with water in an exothermic reaction; means for enriching a hydrogen-containing gaseous medium with water at a water addition rate commensurate with a consumption rate at which hydrogen is being consumed in the fuel cell device; means for passing the water-enriched hydrogen-containing gaseous medium through said bed from said inlet portion to said outlet portion of said enclosed space for the water contained in said water-enriched gaseous medium to exothermically react with said solid material and remove heat from said material bed by convection; means for supplying said gaseous medium from said outlet portion to the fuel cell device at a supply rate at least equal to said consumption rate; and means for enhancing the removal of heat from said bed to achieve a heat removal rate sufficient to maintain a temperature differential between said inlet portion and said outlet portion below a level at which local overheating of said bed occurs, including means for recirculating a portion of said gaseous medium from said outlet portion to said inlet portion, and means for cooling at least said portion of said gaseous medium that is being recirculated by said recirculating means. A method of replenishing hydrogen consumed in a fuel cell device, comprising the steps of confining a gas-permeable bed of a solid material that releases hydrogen on contact with water in an exothermic reaction in an enclosed space having an inlet portion and an outlet portion; enriching a hydrogen-containing gaseous medium with water at a water addition rate commensurate with a consumption rate at which hydrogen is being consumed in the fuel cell device; passing the water-enriched hydrogen-containing gaseous medium through said bed from the inlet portion to the outlet portion of said enclosed space for the water contained in said water-enriched gaseous medium to exothermically react with said solid material and remove heat from the bed by convection; supplying said gaseous medium from the outlet portion to the fuel cell device at a supply rate at least equal to the consumption rate; and enhancing the removal of heat from the bed to achieve a heat removal rate sufficient to maintain a temperature differential between the inlet portion and the outlet portion below a level at which local overheating of said bed occurs, including recirculating a portion of the gaseous medium from the outlet portion to the inlet portion, and cooling at least that portion of the gaseous medium that is being recirculated.
