Patent number: 9929415Abstract: A fuel cell system includes a fuel cell, a first combustor, a second combustor, a first heating gas return channel, a second heating gas return channel and a gas supplier. The fuel cell includes a solid electrolyte cell with an anode and a cathode. The first combustor supplies a heating gas to the cathode. The second combustor supplies a heating gas to the anode. The first heating gas return channel is arranged to mix at least some exhaust gas discharged from the cathode with the heating gas from the first combustor. The second heating gas return channel is arranged to mix at least some exhaust gas discharged from the cathode with the heating gas from the second combustor. The gas supplier is connected to the first heating gas return channel for supplying the exhaust gas from the cathode to mix with the heating gas of the first combustor.Type: GrantFiled: April 13, 2015Date of Patent: March 27, 2018Assignee: Nissan Motor Co., Ltd.Inventors: Kazufumi Takeuchi, Tatsuya Yaguchi

Patent number: 9406949Abstract: A fuel cell system is provided with a fuel cell, a first combustor, a first heating gas return channel and a gas supplier. The fuel cell includes a solid electrolyte cell with an anode and a cathode. The fuel cell generates power by reacting a hydrogen-containing gas and an oxygen-containing gas. The first combustor selectively supplies a heating gas to the cathode of the fuel cell. The first heating gas return channel mixes at least some exhaust gas discharged from the cathode with the heating gas of the first combustor such that a mixed heating gas of the exhaust gas and the heating gas is supplied to the cathode. The gas supplier connected to the first heating gas return channel for supplying the exhaust gas from the cathode to mix with the heating gas of the first combustor.Type: GrantFiled: July 2, 2010Date of Patent: August 2, 2016Assignee: Nissan Motor Co., Ltd.Inventors: Kazufumi Takeuchi, Tatsuya Yaguchi

Patent number: 8815461Abstract: A solid electrolyte fuel cell system includes a reformer to produce a hydrogen-rich reformed gas from fuel, oxygen and water, and a stack structure including a stack of fuel cell units each receiving supply of the reformed gas and air, and producing electricity. The fuel cell system further includes a reformed gas cooler to cool the reformed gas supplied from the reformer to the stack structure, and a temperature control section to control operation of the reformed gas cooler in accordance with an operating condition such as a request output of the stack structure. The reformed gas cooler includes a device such as a heat exchanger for cooling the reformed gas with a coolant such as air.Type: GrantFiled: November 28, 2008Date of Patent: August 26, 2014Assignee: Nissan Motor Co., Ltd.Inventors: Kazufumi Takeuchi, Hiromichi Miwa, Masaharu Hatano, Keiko Kushibiki, Tatsuya Yaguchi
