Mount structure for fuel cell stack
View Patent ↗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.
1. A mount structure for a fuel cell stack for a purpose of arranging the fuel cell stack, which comprises a plurality of stacked power generation cells for generating electrical energy by electrochemical reactions between a fuel gas and an oxygen-containing gas, in a motor room of a fuel cell vehicle,
wherein a motor is disposed below the fuel cell stack;
the mount structure comprising:
a mount member configured to fix the fuel cell stack and the motor to a vehicle body; and
a bracket member configured to connect the mount member and the fuel cell stack; and
wherein an upper surface of the bracket member, which is connected to a lower portion of the fuel cell stack, has an upper surface cut formed by cutting the bracket member in a depth direction, and the upper surface cut extends in a surface direction of the upper surface; and
a lower surface of the bracket member, which is opposite to the upper surface, has a lower surface cut formed by cutting the bracket member in the depth direction, and the lower surface cut extends in a surface direction of the lower surface.
2. The mount structure for the fuel cell stack according to claim 1 , wherein a length of the upper surface cut in the surface direction is shorter than a length of the lower surface cut in the surface direction.
3. The mount structure for the fuel cell stack according to claim 2 , wherein a cut depth of the upper surface cut is smaller than a cut depth of the lower surface cut.
4. The mount structure for the fuel cell stack according to claim 1 , wherein a cut depth of the upper surface cut is smaller than a cut depth of the lower surface cut.
5. The mount structure for the fuel cell stack according to claim 1 , further comprising a plurality of bolts configured to fix the bracket member and the fuel cell stack,
wherein, among the bolts, a bolt positioned at a rearmost end in a vehicle traveling direction, the upper surface cut, and the lower surface cut are arranged on a same virtual straight line that extends in a vehicle widthwise direction.
6. The mount structure for the fuel cell stack according to claim 1 , further comprising a stack case containing the fuel cell stack,
wherein the bracket member is fixed to the mount member and a lower surface of the stack case.
