Gas jet pump for fuel cell system mounted in vehicle, has feed line through which secondary gas is flowed into precombustion chamber, which is opened tangentially into outside peripheral portion of precombustion chamber

摘要

The gas jet pump has a nozzle (17) which is provided in a region of a precombustion chamber (18), through which the primary gas is flowed into a collector (19). The nozzle is arranged in a plane perpendicular to the flow direction of the primary gas flowing in the central area of the precombustion chamber. The secondary gas is flowed through a feed line (21) into the precombustion chamber. The feed line is opened tangentially into the outside peripheral portion of the precombustion chamber. Independent claims are included for the following: (1) fuel cell system; and (2) use of fuel cell system.
