A gas sensor includes a first electrode having a first main surface and a second main surface opposite to the first main surface; a second electrode having a third main surface facing the second main surface and a fourth main surface opposite to the third main surface; a metal oxide layer disposed between the first electrode and the second electrode, and being in contact with the second main surface and the third main surface; and an insulating film covering at least a part of the first electrode, a part of the second electrode, and at least a part of the metal oxide layer. At least a part of the fourth main surface is exposed to gas which contains a gas molecule including a hydrogen atom. A resistance value of the metal oxide layer decreases when the second electrode is in contact with the gas molecule.

A vehicle energy storage system is disclosed herein that addresses at least some of the issues described above. The system includes an energy storage compartment with an access mechanism. Safety mechanisms are provided that ensure energy cartridges are properly installed in the compartment, that the access mechanism properly closes, and that notify a user when the cartridges are improperly installed and/or are faulty.

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.

A vehicle battery mounting structure includes i) a battery frame that includes a battery upper frame made of fiber-reinforced resin and a battery lower frame made of fiber-reinforced resin, and that is arranged on a vehicle body lower side of a floor panel and supports a battery; and ii) a ductile member that has an upper main body portion joined to the battery upper frame, an upper flange portion continuously provided on a vehicle width direction outside end portion of the upper main body portion, a lower main body portion joined to the battery lower frame, and a lower flange portion continuously provided on a vehicle width direction outside end portion of the lower main body portion, in which the upper flange portion and the lower flange portion are overlapped and fixed to a lower surface side of the floor panel.

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.

In order to limit entry of a fuel cell stack into a passenger compartment by a simple structure, the fuel cell stack is accommodated in an accommodating compartment formed at a rear of a passenger compartment. A force receiving member is arranged forward with respect to the fuel cell stack and below the fuel cell stack so that rearward force acts on the force receiving member at the time of vehicle collision. When the rearward force acting on the force receiving member due to vehicle collision is larger than a predetermined upper limit value, the rearward force is converted into upward force, and the upward force is transmitted to a forward bottom surface of the fuel cell stack, whereby a forward end part of the fuel cell stack is lifted up with respect to a rearward end part of the fuel cell stack upon vehicle collision.

An electrically driven vehicle comprises: a body frame arranged in a holding compartment formed in front of a passenger compartment; a suspension member fastened to the body frame in the holding compartment through a rear side fastening structure; and a fuel cell stack supported on the suspension member through a rear side mount at a position in front of the rear side fastening structure. When a serious collision occurs, the fuel cell stack moves rearward and strikes the fastening structure whereby the fastening structure breaks and thereby suspension member separates from the body frame and the fuel cell stack moves downward and heads toward the inside of the shelter space between the holding compartment and a road surface.

There is provided a saddle-ridden type fuel cell vehicle. The fuel cell vehicle includes: a body frame; a steerable wheel; a driving wheel; a motor; a fuel cell; a fuel tank; and a tank valve. The body frame includes: a head pipe; a down frame portion; a pair of upper main frame portions; a pair of lower main frame portions; and up frame portions. A tank placement portion is formed in a region encircled by the upper main frame portions and the lower main frame portions in the middle portion of the body frame in the front and rear direction. The fuel tank is placed on the tank placement portion so that an axis thereof extends in the front and rear direction. A guard frame is installed between the up frame portions to traverse the rear of the tank valve in a right and left direction.

A thermal management system of a fuel cell vehicle includes a cold start loop which heats a coolant that flows through a fuel cell during a cold start of the fuel cell, and a cooling loop which moves a coolant that cools the fuel cell.

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.
