An integrated fuel cell, FC, module, for an electrical system in a heavy-duty vehicle is disclosed. The module includes a fuel cell stack, a compressor, a bleed valve, and an air-cooled brake resistor, where the bleed valve is configured to divide an air flow from the compressor into a first air flow and a second air flow, where the first air flow is fed to the fuel cell stack and the second air flow is fed to the air-cooled brake resistor, where the fuel cell stack, the compressor, the bleed valve, and the air-cooled brake resistor are enclosed in a common casing structure.

A suspension arrangement is provided for an energy storage system of a vehicle comprising a frame. The suspension arrangement includes a set of first bracket portions, wherein the first bracket portions are spaced apart from each other and connectable to a first portion of the frame; a set of second bracket portions. Each second bracket portion is connected to a respective one of the first bracket portions by a first stretchable connector arrangement to form a first encircling portion configured to suspend a first gas tank. A set of third bracket portions is provided, wherein each third bracket portion is connected to a respective one of the first bracket portions by a second stretchable connector arrangement to form a second encircling portion configured to suspend a second gas tank, the set of third bracket portions being arranged on an opposite side of the set of first bracket portions compared to the position of the set of second bracket portions.

A fuel cell vehicle includes a first tank, a second tank, first and second valves for releasing gas, a gas passage for supplying gas to a fuel cell via the first and second valves, a pressure-reducing valve for decompressing the gas, side members disposed on the respective sides of the vehicle, and a motor disposed rearward of the second tank and configured to drive wheels. The first tank is not disposed downstream of the second tank, on the gas passage. The pressure-reducing valve is disposed in a region located rearward of a rear end of the second tank in a vehicle front-rear direction, forward of a rear end of the motor in the vehicle front-rear direction, and between one of the side members and an extended line extended in the vehicle front-rear direction from a side wall of the motor. The pressure-reducing valve is disposed on the second valve side.

A fuel cell vehicle comprising: a hydrogen tank which is mounted on the vehicle so as to have a center axis generally parallel to a front/rear direction of the vehicle; a high-voltage electric component which is positioned either forward or rearward of the hydrogen tank and which operates on high voltage; an aftercooler placed between the hydrogen tank and the high-voltage electric component to cool compressed air; and a fuel cell stack which is supplied with the cooled compressed air.

A fuel cell-equipped vehicle includes a fuel cell stack disposed in a front space of a vehicle body by a partition member, and an air conditioner disposed in a rear space of the vehicle body separated by the partition member, wherein external air is introduced into the air conditioner through an external air intake port formed at a portion of the partition member located on a first side with respect to a center in a vehicle width direction of the vehicle body, downstream end of the exhaust duct configured to discharge a reaction gas in the casing communicates with an outside of the vehicle body at a portion located on a second side with respect to the center in the vehicle width direction.

A fuel cell stack includes a bracket and a boss. The bracket includes an attachment surface. The bracket includes an attachment and detachment hole and an opening hole. The boss includes a bearing surface and a locking surface part. The locking surface part is connected to the bearing surface and protrudes in an outside direction such that at least a part of the locking surface part overlaps with the attachment surface part viewed from an attachment direction when a center of the attachment and detachment hole coincides with a center of the bearing surface.

A vehicle includes an electrical device in which a high-voltage part is disposed within a case, and a fuel tank. The high-voltage part is disposed near a first side end of the case in a vehicle width direction. The fuel tank has a first end portion in the vehicle width direction and a second end portion opposite to the first end portion. When a collision load equal to or greater than a predetermined value is applied to the fuel tank from the outside in a vehicle front-rear direction, the fuel tank is configured to horizontally rotated about the first end portion of the fuel tank, and the second end portion of the fuel tank is configured to contact the second side end of the electrical device.

A protection bar is arranged between a fuel cell casing and a DC-DC converter in the left-right direction of a fuel cell vehicle. Two fastening surfaces, each being a part of the fuel cell casing, and an FDC flange, which is a part of the DC-DC converter, are fastened and fixed to each other, with one being vertically superimposed on the other, in a space above or below the protection bar.

A fuel cell vehicle includes a fuel cell module accommodated in a fuel cell accommodation space disposed in a front portion of the vehicle, a hydrogen circulation flow path configured to recirculate anode off-gas that is discharged from a fuel cell constituting the fuel cell module to the fuel cell, and a hydrogen pump provided in the hydrogen circulation flow path and fixed to a lower portion of the fuel cell module. The hydrogen pump is fixed to the fuel cell module via a bracket and the deformation strength of the bracket is set to be lower than a load input from a wall portion behind the fuel cell accommodation space at the time of collision of the vehicle.
