Patent number: 11637297Abstract: A fuel cell system includes a fuel cell, a cathode off-gas discharge channel, a gas-liquid separator, and a cover member. The gas-liquid separator includes a body, a first discharge channel including a first valve seat at an end, and a first valve device including a first valve element and a first driver. The cover member covers at least the first discharge channel and the first valve seat in the gas-liquid separator, and includes a gas channel defining portion that defines a gas channel communicating with the cathode off-gas discharge channel between the cover member and the gas-liquid separator. The gas channel is configured such that a cathode off-gas flowing into the cover member comes into contact with the first discharge channel and the first valve seat and does not come into contact with the first driver.Type: GrantFiled: October 7, 2021Date of Patent: April 25, 2023Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, ASIN CORPORATIONInventors: Takami Hosoi, Hiroaki Nishiumi, Takashi Mishima, Hitoshi Okuno, Toshihide Yamada

Patent number: 10991958Abstract: A gas and water discharge unit for a fuel cell system that can be prevented from freezing even when it is formed using resin material. The unit includes a gas-liquid separator for separating produced water from fuel off-gas discharged from a fuel cell device, a gas and water discharge valve disposed downstream of the gas-liquid separator, and a resin unit body integrally formed with the gas-liquid separator and the gas and water discharge valve, in which the inside of the unit body includes a first channel with a valve seal at an end thereof on the gas and water discharge valve side, the first channel allowing communication between the gas-liquid separator and the gas and water discharge valve, a second channel communicating with the first channel via the gas and water discharge valve, and a heated water channel surrounding at least one of the first or second channel.Type: GrantFiled: May 13, 2019Date of Patent: April 27, 2021Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, AISIN SEIKI KABUSHIKI KAISHAInventors: Takami Hosoi, Hiroaki Nishiumi, Takashi Mishima, Koichi Kashiwagi, Hitoshi Okuno
