Patent number: 9531023Abstract: An exhaust state control device for a fuel cell for a mobile unit includes an exhaust gas temperature sensor (17) that measures the temperature of exhaust gas in a discharge passage that discharges the exhaust gas from the main body of the fuel cell, and an ambient temperature sensor (19A) that measures the temperature of ambient air to which exhaust gas is to be discharged. If, based on the difference between the exhaust gas temperature and the ambient temperature, it is determined that white smoke is generated, it is determined whether a condition to reduce white smoke is satisfied. When a first condition is satisfied, a process to reduce white smoke is activated. When a second condition, which requires further reduction of white smoke than under the first condition, is satisfied, a process to suppress the generation of white smoke is activated.Type: GrantFiled: April 4, 2013Date of Patent: December 27, 2016Assignee: Toyota Jidosha Kabushiki KaishaInventors: Hiromi Tanaka, Keigo Suematsu, Takahide Izutani
