摘要:
A fuel cell apparatus is formed by connecting four stacks via a supply/discharge box. A cooling water supply opening and a cooling water discharge opening are short-circuited by a cable so as to eliminate the electric potential difference therebetween. To avoid hindrance of gas flow due to water droplets, a drain port for discharging water droplets is provided near a fuel gas discharge opening of the supply/discharge box. Each stack is formed by clamping end plates disposed on opposite ends of stacked cells through the use of upper and lower tension plates. The thus-formed fuel cell apparatus is housed in an outer case that has a sealed construction for preventing penetration of foreign substances. Thus, the apparatus achieves a size reduction and an improvement in practicality.

A housing case that houses a fuel cell is provided with mounts for fixing two ends of a lower surface of an end plate that retains stacked unit cells of the fuel cell, and a mount for fixing a central portion of a lower surface of another end plate. Using these three mounts, the fuel cell is fixed to the housing case.

An exhaust gas processing device (16) intermittently introduces anode off-gas from a fuel cell (12). The exhaust processing device (16) discharges the anode off-gas after diluting it with dilution gas. The exhaust gas processing device (16) includes a dilution container (25) and a partition plate (28), which divide the interior of the dilution container (25) into a first chamber (26) and a second chamber (27). The partition plate (28) has a clearance (29), which connects the first chamber (26) and the second chamber (27) to each other. The exhaust gas processing device (16) includes a discharge portion (32) provided in the first chamber (26), a dilution gas inlet portion (30) provided in the first chamber (26), and an anode off-gas inlet portion (31) provided in the second chamber (27).
摘要:
A fuel cell apparatus includes a stack of fuel cells, first and second end plates disposed at opposite ends of the stack of fuel cells to press the stack of fuel cells and being connected by a fastening member, and a pressure plate disposed inboard of the first end plate. A concave portion is formed at an inboard surface of the first end plate and a convex portion is formed at an outboard surface of the pressure plate. The convex portion contacts the concave portion. The first and second end plates are coupled to the fastening member (or, a tension plate) by a serration and a bolt. An adjusting portion is formed in the first end plate, and the concave portion is formed in the adjusting portion. A load variance decreasing mechanism is disposed in series with the contact portion of the convex portion and the concave portion. A recess is formed in an electrical insulator disposed inboard of the pressure plate, and the pressure plate is disposed in the recess. The convex portion may include a spherical surface or a cylindrical surface. The load variance decreasing mechanism may include a plurality of sets of coned disk springs disposed in series with each other. The fuel cell apparatus may include an attaching member constituting a portion of the fuel cell apparatus and attaching the fuel cell apparatus to a vehicle.

A fuel cell system includes an exhaust pipe through which anode purge gas is discharged into the atmosphere, a heat medium passage through which heat medium is flowed, a circulation pump for circulating the heat medium through the heat medium passage, a heat exchanger provided in the heat medium passage, a heat exchanger fan for generating airflow through the heat exchanger, and a guide by which the airflow is guided so as to diffuse the anode purge gas. The circulation pump and the heat exchanger fan are operated during anode purge in such a way that the heat exchanger fan is operated regardless of the heat medium temperature, and a flow rate of the heat medium flowing through the heat medium passage is zero or lower than a flow rate when output of a fuel cell is maximum.

An electric motor control apparatus includes a phase correction portion that generates and outputs an amount of phase correction with which to correct a phase of a signal from a position sensor detecting a position of a magnetic pole of an electric motor. The phase correction portion generates and outputs an energization stop signal in a case where a rotation speed of the electric motor is within a predetermined range and stores an amount of phase correction generated therein according to a comparison between a signal from the position sensor or a first phase and an induced voltage of the electric motor to output the amount of phase correction.
