A fuel cell vehicle comprises a fuel cell stack that is mounted in a housing box placed on a front or rear side of a passenger compartment. The fuel cell stack is housed in a stack casing, and the stack casing is mounted on a frame of the housing box via a stack mount. The stack mount includes: a stack-side bracket provided in the stack casing; a frame-side bracket provided in the frame; and a fixing member configured to fix the stack-side bracket and the frame-side bracket together. The stack mount has at least either one of: (a) a first structure in which a cutout portion is formed in the stack-side bracket on one side thereof which faces a proximal end portion, the proximal end portion being one of a front end portion and a rear end portion of the fuel cell vehicle which is closer to the housing box; or (b) a second structure in which a cutout portion is formed in the frame-side bracket on one side thereof which faces a distal end portion, the distal end portion being another one of the front end portion and the rear end portion of the fuel cell vehicle which is farther from the housing box.

A mount structure includes a mount member, and a bracket member. An upper surface of the bracket member, which is connected to a lower portion of a fuel cell stack, includes an upper surface cut formed by cutting the bracket member in a depth direction, and the upper surface cut extends in a surface direction. A lower surface of the bracket member, which is opposite to the upper surface, includes a lower surface cut formed by cutting the bracket member in the depth direction, and the lower surface cut extends in the surface direction.

In a fuel cell vehicle, a stack case containing a fuel cell stack is mounted in a front box. Exhaust ducts are connected to openings formed in an upper panel of the stack case. A right exhaust duct connected to the exhaust ducts is opened to a right fender part, and a left exhaust duct connected to the exhaust ducts is opened to a left fender part.

In order to provide a fuel cell powered vehicle testing system capable of performing a test of a power system of a fuel cell powered vehicle by a simpler facility, includes: a dynamometer which is connected to an output shaft of an electric motor mounted on a fuel cell powered vehicle for applying a simulation travelling load to the electric motor; and a supply power simulator adapted to simulate an operation of the fuel cell mounted on the fuel cell powered vehicle and to apply power to the electric motor, the power being to be supplied from the fuel cell to the electric motor.

There is provided a technique of improving an intake structure that takes in the outside air in a fuel cell vehicle. A fuel cell vehicle 10 includes first and second grilles 11 and 12 that are configured to be open forward and take in the outside air. An air intake 100 is placed in a vehicle inner space 10r of the fuel cell vehicle 10. The air intake 100 is placed in a location behind and above the first grille 11 and is configured to take in the air as a reactive gas that is to be supplied to a fuel cell 21. A flow path member 120 is placed in a location in front of and below the air intake 100 and behind the first grille 11. The flow path member 120 has an inclined wall portion 121 that is arranged to face the first grille 11 and is inclined obliquely upward from front to rear.

An apparatus, including: a vehicle battery located in, on, or at, an electric or hybrid vehicle; a vehicle fuel cell located in, on, or at, the electric or hybrid vehicle; an electrolyzer located in, on, or at, the electric or hybrid vehicle, wherein the vehicle battery supplies electrical power to the electrolyzer when the vehicle fuel cell is operational; an Oxygen exhaust system located in, on, or at, the electric or hybrid vehicle; and a Hydrogen storage tank located in, on, or at, the electric or hybrid vehicle. The vehicle fuel cell generates electrical power and produces water or water vapor. The electrolyzer receives the water or water vapor and produces Oxygen and Hydrogen from the water or water vapor. The Oxygen exhaust system emits or releases the Oxygen into the atmosphere. The Hydrogen storage tank receives and stores the Hydrogen.

A fuel cell vehicle and associated fluid line arrangement include a main branch, which passes through a fuel cell unit, and a secondary branch that branches off the main branch and includes a flow limiter having a tube element, the internal cross section of which decreases downstream with respect to a flow direction, and a piston element moveable at least partially downstream along a movement path in the tube element counter to a restoring force between an open position and a restricting position. The flow limiter provides a fluid-carrying cross section of passage that is smaller than in the open position formed between the piston element and the tube element to limit mass flow through the secondary branch between a maximum and minimum mass flow.

A fuel cell stack includes a stack body, a stack casing, and an exhaust duct. The stack body includes a first end, a second end, a bottom, a top, a side, and a downwardly inclined portion. The top has a substantially flat portion with an end point. The side extends between the top and the bottom and between the first end and the second end. The downwardly inclined portion connects the end point of the substantially flat portion and the side. The stack casing accommodates the stack body. The stack casing includes an upper wall and a side wall. The side wall is opposite to the side of the stack body. The exhaust duct is connected to the upper wall of the stack casing. The exhaust duct has an opening on the upper wall. The opening is arranged between the end point and the side wall.
