Abstract

A compact fuel battery system is provided that has an integrated hydrogen generator. This fuel battery system 1 is provided with a hydrogen generator 10 and a fuel battery cell 20. The hydrogen generator 10 is provided with a plate-shape dielectric 2 having a raw material gas flow path surface 11 in which a raw material gas flow path 13 is formed. An electrode 3 faces the back surface 12 of the dielectric 2. A hydrogen separation membrane 5, which has a first surface 18 and the second surface 19, closes an opening of the raw material gas flow path 13. Furthermore, the hydrogen generator 10 isprovided with a high-voltage power supply 6 which generates electric discharge between the hydrogen separation membrane 5 and the electrode 3. The fuel battery system is characterized in that the second surface 19 of the hydrogen separation membrane 5 of the hydrogen generator is arranged facing the fuel electrode 21 of the fuel battery cell 20.

Description

technical field [0001] The present invention relates to a fuel cell system provided with a hydrogen generating device capable of generating high-purity hydrogen from hydrogen raw materials at a high yield. Background technique [0002] A typical device that uses hydrogen as fuel is a fuel cell. Fuel cells require high purity hydrogen to operate, and the hydrogen purity standard for fuel cells is currently defined as 99.97% in ISO 14687-2. If a device capable of directly supplying high-purity hydrogen to a fuel cell can be provided, it will be possible to manufacture a small fuel cell system having an integrated fuel cell and a hydrogen generating device. Providing such a fuel cell system would expand the possible applications of fuel cells. [0003] An example of a known method for generating hydrogen for fuel cells is the steam reforming of hydrocarbon gases, such as methane. However, steam reforming requires processing at high temperatures using expensive catalysts such...
