In a mounting structure for a fuel cell drive system, a mount member includes a first mount and a second mount. The first mount connects the first end of a stack case to the first frame. The second mount connects the second end of an auxiliary device case to the second frame. The fuel cell drive system includes a first connecting member and a second connecting member. The first connecting member connects the stack case and a motor to each other. The second connecting member connects the auxiliary device case and a speed reducer to each other.

A modular chassis with one or more modular packs configured to couple to an adjacent modular pack and/or subframe to form a modular chassis for a vehicle. Each of the one or more modular packs may be configured to contain and carry or otherwise support a subsystem, a component, or a component of a subsystem for operation of the vehicle. One or more modular packs within a modular chassis may be empty and serve only a support or structural function for the modular chassis.

To provide a fuel cell system configured to charge a battery with maintaining the independence and redundancy of a fuel cell and a battery as power sources. A fuel cell system for air vehicles, wherein the fuel cell system comprises a fuel cell, a battery, a motor and a controller; wherein the fuel cell and the battery are connected to the motor as independent power sources, and the motor includes a double three-phase winding that uses a double inverter; and wherein, when normal output is requested from the motor, the controller operates the motor by a predetermined first output from the fuel cell, and the controller charges the battery by a torque generated in the motor.

A two-wheeled motor vehicle includes: a vehicle body frame; a rear wheel unit swingably supported on the vehicle body frame; a fuel cell unit supported on the vehicle body frame; a fuel tank extending rearwardly from the fuel cell unit over the rear wheel unit; and a secondary cell that is charged with electric power from the fuel cell unit and disposed below the fuel cell unit and the fuel tank.

In a saddle-riding-type electric vehicle fuel cell stack fixation structure, a vehicle body frame includes: a pair of right and left main frames that extend rearward from a head pipe and that are arranged on an outer side in a vehicle width direction of a fuel cell stack; a pair of right and left downward frames that extend rearward from the head pipe and that are arranged below the pair of right and left main frames; and a cross member that bridges a space in a vehicle width direction between at least the right and left downward frames and that fixes the fuel cell stack.

In order to secure a driving performance of an electric vehicle while stably supporting a fuel cell stack, a fuel cell stack generating electric power, a motor generator, and an electrical adjuster are accommodated in an accommodation compartment formed at a front side of a passenger compartment in a vehicle length direction. The electric motor and the electrical adjuster are housed in a common, bottom casing and the bottom casing is arranged at a bottom of the accommodation compartment. A stack support surface which is flat and extends in substantially a horizontal direction is formed at a top of the casing. The fuel cell stack is arranged above the casing and is supported by the casing through mounts arranged on the stack support surface.

A vehicle which includes a fuel cell, a receptacle, a lid, and a fixing pin, and which stores a detection of the open state during a period from a time point of a latest end of operation of the vehicle to a time point of input acceptance of a start-up instruction. If a detection of an open state has been stored in a memory at a time point of input acceptance of a start-up instruction, then the vehicle executes a retry operation of temporarily moving the fixing pin of the fixed position to the released position and thereafter moving the fixing pin again to the fixed position during an operating period of the vehicle from the time point of input acceptance of the start-up instruction.

A piping member that is used for a moving body equipped with a fuel cell and that is configured to suppress potential troubles caused by drainage water of the fuel cell. A fuel cell vehicle includes an exhaust pipe that is a piping member configured to discharge drainage water and exhaust gas of a fuel cell. The exhaust pipe includes an extended portion, a curved portion and an opening end portion and is mounted such that the exhaust pipe opens downward on the rear side of the fuel cell vehicle. The exhaust pipe is configured such that an inner wall surface of a wall portion of the opening end portion located on the front side of the vehicle is inclined from the rear side toward the front side of the fuel cell vehicle to be extended to an opening, in the state that the exhaust pipe is mounted to the fuel cell vehicle.

A method of discharging water from a mobile object, which includes a fuel cell, a gas-liquid separator, and a circulation pump, comprises: an inclined state detection step of detecting an inclined state of the mobile object with respect to a horizontal plane; a scavenging start step of starting to supply scavenging gas at a predetermined first supply flow rate to a gas flow path in the fuel cell, by driving the circulation pump; and a supply flow rate increase step of increasing, when the mobile object is in a predetermined inclined state in which an outlet of the gas flow path is directed upward against a direction of gravity, a rotational speed of the circulation pump so that the supply flow rate of the scavenging gas is increased to a second supply flow rate higher than the first supply flow rate after a predetermined period from starting to supply the scavenging gas.

The present invention provides a fuel cell vehicle that is capable of suppressing rotation of a fuel cell when a vehicle collision occurs and minimizing damage to the fuel cell and auxiliary apparatuses. A fuel cell vehicle 1 comprises: a radiator 11 provided in a front room 10; and a fuel cell assembly 12 provided in a vehicle rear direction with respect to the radiator 11 in the front room 10. The fuel cell assembly 12 comprises: an assembly frame 60; and a fuel cell apparatus group 61 that includes a fuel cell 70 and an auxiliary apparatus, the fuel cell apparatus group 61 being integrally mounted to the assembly frame 60. The assembly frame 60 protrudes more than the fuel cell apparatus group 61, toward the radiator 11 at the front side. The fuel cell assembly 12 is installed in the front room 10 such that a height of a front edge part A of the assembly frame 60 at a front side approximately matches a height of a center of gravity P of the entire fuel cell assembly 12.
