Embodiment Construction

[0044] Hereinafter, a fuel cell system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the description of the fuel cell system, the hydrogen generating apparatus according to the present invention will also be described in detail.

[0045] The fuel cell system according to the present embodiment is provided in an electric vehicle. The fuel cell system includes a hydrogen separation membrane fuel cell (hereinafter referred to as "HMFC") and a hydrogen generating apparatus according to the present invention. The HMFC includes an electrolyte membrane where a proton-conducting ceramic is disposed on the surface of a hydrogen-permeable metal membrane.

[0046] In this example, gasoline and cathode off-gas containing water vapor were used as reactants when the reforming reaction was carried out. Cathode exhaust is emitted from the oxygen electrode (cathode) of the HMFC. The combustion reaction proceed...

Abstract

A hydrogen generation device (110) includes a catalyst (162); a sulfur-trap member (164); a soot-trap member (166); a pair of reformers (112, 114); and a control portion (170). In each reformer (112, 114), a reforming reaction is carried out to generate hydrogen-containing gas using gasoline and cathode off-gas on the catalyst (162), and an exothermic reaction is carried out to heat the catalyst (162) using anode off- gas and air. The control portion (170) executes a control such that the reactant and the exothermic material are alternately supplied to each reformer (112, 114), whereby the reforming reaction and the exothermic reaction are alternately carried out in each reformer (112, 114). A fuel cell system (100) includes the hydrogen generation device (110).

Description

technical field [0001] The present invention relates to a hydrogen generating apparatus which alternately generates hydrogen through a reforming reaction using a catalyst, and regenerates the catalyst through a regeneration reaction. The regeneration reaction regenerates the catalyst by heating it for the next reforming reaction. The invention also relates to a fuel cell system comprising such a hydrogen generating device. Background technique [0002] In electric vehicles, fuel cells are used as a power source. There is therefore a need to provide hydrogen for power generation in fuel cells or reactants for hydrogen production. [0003] Where hydrogen itself is provided, the hydrogen is stored by (i) compressing and storing the hydrogen in a high pressure vessel, (ii) liquefying and storing the hydrogen in a tank, or (iii) using a hydrogen storage alloy or Hydrogen getter to provide hydrogen. When hydrogen is stored in a high pressure vessel as described in (i), only a ...
