Title:

FUEL CELL SYSTEM

Document Type and Number:

WIPO Patent Application WO/2012/070367

Kind Code:

A1

Abstract:

The present invention effectively circulates waste-hydrogen-containing gas regardless of whether the flow rate of hydrogen-containing gas increases or decreases, and simplifies a system and makes the system more compact. The present invention is a fuel cell system comprising: cell unit (11) that generates electricity by separating waste-hydrogen-containing gas and hydrogen-containing gas from each other and then causing the gasses to flow together; a feed path (20a) provided with an ejector (22) for recirculating waste-hydrogen-containing gas discharged from the cell unit (11) to the cell unit (11); and a bypass path (20b) for causing hydrogen-containing gas that flows towards the cell unit (11) to bypass the ejector (22). The fuel cell system is characterized in that when the flow rate of hydrogen-containing gas to be supplied to the cell unit (11) is less than a prescribed flow rate, the hydrogen-containing gas is made to flow to the feed path (20a) provided with the ejector (22), but when the flow rate of hydrogen-containing gas is greater than a prescribed flow rate, the hydrogen-containing gas is made to flow to the bypass path (20b).
