Capacitor module

A fuel evaporator composed of an evaporation chamber which evaporates a raw liquid fuel by a high temperature thermal medium to provide a raw fuel gas is disclosed. The evaporation chamber comprises a plurality of evaporation chambers serially connected to each other in a ventilation manner, and at least one raw liquid fuel injector for injecting the raw liquid fuel being provided on each of said plurality of evaporation chambers.

Fuel evaporator

A fuel cell system comprises a fuel cell stack an evaporator a reforming device a supercharger an offgas heating device and a catalytic combustion chamber Offgas exhausted from the fuel cell stack is burnt in the catalytic combustion chamber and the burnt offgas is introduced to the evaporator to be heat exchanged with a reforming raw fuel and reforming air. The burnt offgas cooled by means of the heat exchange is introduced to the offgas heating device to be used as a heat source for heating the offgas exhausted from the fuel cell stack The offgas can be heated by the burnt offgas, and the moisture in the offgas can be vaporized and introduced to the catalytic combustion chamber

Recovery system of heat energy in a fuel cell system

In a fuel evaporator provided with an evaporation chamber that produces raw fuel gas FG by vaporizing raw fuel liquid by heat received from a plurality of heat medium tubes through which a high temperature heat medium passes, a raw fuel injection portion that injects raw fuel liquid onto the heat medium tubes is situated in the evaporation chamber . The heat medium tubes are arranged sparsely near the raw fuel injection portion and densely away from it. A catalytic combustor is provided adjacent to the bottom surface of the evaporation chamber to form the high temperature heat medium. Such a fuel evaporator efficiently vaporizes raw fuel liquid and can be suitably applied in a fuel cell system for a fuel cell-powered automobile.

A fuel evaporator raw fuel injection apparatus A includes an evaporator having an evaporating chamber in which raw fuel liquid FL is evaporated by a high temperature heating chamber (heating gas) into raw fuel gas, and which is provided with a first injection portion (fuel injection portion A) that injects the raw fuel liquid FL into the evaporating chamber , and a second injection portion (air injection portion A) that injects gas or liquid (air A) with a prescribed directional property into the raw fuel liquid FL injected from the fist injection portion (fuel injection portion A), adequately atomizes and disperses raw fuel liquid and achieves highly efficient evaporation of raw fuel liquid.

Evaporator raw fuel injection apparatus

A fuel reforming apparatus is provided for generating a hydrogen-rich gas. The fuel reforming apparatus includes an evaporator comprising an evaporation chamber for evaporating the fuel vapor by evaporating a hydrocarbon fuel-water mixture by an evaporator using a combustion gas formed in a combustor; a heating chamber for heating the fuel vapor by a combustion gas output from the evaporation chamber; and a guiding path for guiding the combustion gas output from the evaporation chamber to the heating chamber along the floor of the evaporating room. In the heating chamber, the fuel vapor generated in the evaporation chamber is uniformly heated in an atmosphere with a homogeneous temperature of the combustion gas output from a heating medium tube, while the fuel vapor is circulating in the vapor tube.

Fuel reforming apparatus

A warm-up apparatus for a fuel evaporator comprises: a catalyst combustor for catalytically burning exhaust gas from a fuel cell to produce combustion gas and supplying the fuel evaporator which evaporates raw fuel liquid with the produced combustion gas as an evaporation heat source; an exhaust gas passage for transferring exhaust gas to the catalyst combustor; and a combustion gas transferring device including a fuel injection portion and a combustion catalyst , and injecting fuel from the fuel injection portion onto the combustion catalyst, where the fuel is catalytically burned to produce combustion gas, and thereafter transferring the produced combustion gas to the catalyst combustor. The combustion gas transferring device is positioned on one side of said exhaust gas passage.
