Abstract
A fuel cell unit includes; a fuel cell module including a fuel cell stack including: a stacked body in which unit cells are stacked; a pair of end plates sandwiching the stacked body in a stacking direction; a facing member facing an outer surface of the stacked body extending along the stacking direction; and first and second restriction members arranged between the facing member and the stacked body, and restricting a position of the stacked body in a direction perpendicular to the stacking direction by contacting with the outer surface; and fixing members fixing the fuel cell module to a fixed member.
Claims7
A fuel cell unit comprising:
- a fuel cell module including
- a fuel cell stack including:
- a stacked body in which unit cells are stacked;
- a pair of end plates sandwiching the stacked body in a stacking direction;
- a facing member facing an outer surface of the stacked body extending along the stacking direction;
- and
- first and second restriction members arranged between the facing member and the stacked body, and restricting a position of the stacked body in a direction perpendicular to the stacking direction by contacting with the outer surface;
- and
- fixing members fixing the fuel cell module to a fixed member,
- wherein
- the stacking direction includes a first side and a second side opposite to the first side,
- a center of gravity of the fuel cell module is positioned in the first side of the stacking direction from a region surrounded by the fixing members,
- the first restriction member restricts a first part of the stacked body positioned in the first side of the stacking direction from a center of the stacked body,
- the second restriction member restricts a second part of the stacked body positioned in the second side of the stacking direction from the center of the stacked body, and
- the first and second restriction members are provided such that restriction force restricting the first part of the stacked body is greater than restriction force restricting the second part of the stacked body.
A fuel cell vehicle comprising;
- a vehicle body constitution member;
- and
- a fuel cell unit,
- wherein
- the fuel cell unit includes:
- a fuel cell module including
- fuel cell stack including;
- a stacked body in which unit cells are stacked;
- a pair of end plates sandwiching the stacked body in a stacking direction;
- a facing member facing an outer surface of the stacked body extending along the stacking direction;
- and
- first and second restriction members arranged between the facing member and the stacked body, and restricting a position of the stacked body in a direction perpendicular to the stacking direction by contacting with the outer surface;
- and
- fixing members fixing the fuel cell module to a fixed member,
- the stacking direction includes a first side and a second side opposite to the first side,
- a center of gravity of the fuel cell module is positioned in the first side of the stacking direction from a region surrounded by the fixing members,
- the first restriction member restricts a first part of the stacked body positioned in the first side of the stacking direction from a center of the stacked body,
- the second restriction member restricts a second part of the stacked body positioned in the second side of the stacking direction from the center of the stacked body,
- the first and second restriction members are provided such that restriction force restricting the first part of the stacked body is greater than restriction it restricting the second part of the stacked body, and
- the fixed member is the vehicle body constitution member.
