    摘要: A fuel cell system has a fuel cell, a fuel supply device, a gas discharge valve, a voltage detecting device and a control device. The fuel supply device supplies a fuel gas to the fuel cell. The gas discharge valve discharges the fuel gas into an external environment. The voltage detecting device detects an output voltage of the fuel cell. The control device controls a discharging process when a request for starting the fuel cell is given. The discharging process includes introducing the fuel gas from the fuel supply device into a predetermined passage, opening the gas discharge valve and discharging residuals staying in the passage into the external environment. When the control device receives the request and determines that the output voltage has reached a first threshold before the discharging process has not been completed, the control device starts power generation irrespective of completion of the discharging process.

    摘要: A fuel cell is formed by stacking a membrane electrode assembly and separators alternately. Each of the separators includes first and second metal plates. A coolant flow field is formed between the first metal plate of the fuel cell and the second metal plate of the adjacent fuel cell. A folded section is provided around a coolant supply passage by folding the second metal plate. The folded section forms an inlet which enlarges the sectional area of an opening as a fluid passage between the coolant supply passage and the coolant flow field.
