Patent number: 11072249Abstract: A fuel gas pump of a fuel cell vehicle is fixed to a stack frame and a fuel cell stack via a first bracket and a second bracket so that a rotation axis of a motor is inclined to a reference line along a front-rear direction. The first bracket is fixed by passing a second fastening member through a first notch. The second bracket is fixed by passing a third fastening member through a second notch of a second arm. The first and second brackets are provided such that, when the fuel gas pump rotates, the third fastening member comes off from the second bracket at a timing different from a timing when the second fastening member comes off from the first bracket.Type: GrantFiled: October 29, 2019Date of Patent: July 27, 2021Assignee: Toyota Jidosha Kabushiki KaishaInventors: Tetsuji Aishima, Yoshihiro Kubota

Patent number: 9789755Abstract: A compressor, an intercooler, and a fuel cell stack are housed in a housing compartment. The compressor and the intercooler are connected with each other by upstream side piping, and the intercooler and the fuel cell stack are connected with each other by downstream side piping. The upstream side piping is formed from upstream side first and second pipe parts, and the downstream side piping is formed from downstream side first and second pipe parts. Movement of the compressor and fuel cell stack relative to the intercooler at the time of a heavy collision of the vehicle causes disconnection of the upstream side first and second pipe parts and disconnection of the downstream side first and second pipe parts, to thereby cause communication of the upstream side piping and the downstream side piping with an internal space of the housing compartment.Type: GrantFiled: March 10, 2015Date of Patent: October 17, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tetsuji Aishima, Shigeaki Murata, Hiroyoshi Matsumoto
