Abstract

A movable body includes a fuel cell, a fuel supply means which supplies fuel containing hydrogen to the fuel cell, a limit means which limits the amount of the supplied fuel, a body which includes a space in which an occupant is housed, a conversion means which converts the supplied electric power from the fuel cell to driving force for driving the body, a control portion which controls the operation of the conversion means, and an operating member. The operating member is disposed at a position where the operating member can be operated by the occupant housed in the body, and provides an instruction to execute a control that limits the amount of the supplied fuel using the limit means, without stopping the operation of the control portion.

Claims

1. A movable body comprising:

a fuel cell;

a fuel supply portion for supplying fuel to the fuel cell;

a limit portion for limiting an amount of the fuel supplied by the fuel supply portion;

a body that includes a space in which an occupant is housed;

a conversion portion for converting electric power supplied from the fuel cell to driving force for driving the body;

a control portion that controls an operation of the conversion portion; and

an operating member which is disposed at a position where the operating member can be operated by the occupant housed in the body, and which provides an instruction to execute a control that limits the amount of the supplied fuel using the limit portion, without stopping an operation of the control portion,

wherein the limit portion is a main stop valve for a fuel tank,

wherein the operating member provides the instruction, independently of an ignition switch that provides the instruction on the operation of the control portion, and

wherein the instruction to execute limit control cannot be overridden by the control portion.

2. The movable body according to claim 1, wherein

the operating member has an optical characteristic that is different from an optical characteristic of another operating member that provides an instruction to execute another control.

3. The movable body according to claim 1, wherein

the operating member has a shape that is different from a shape of another operating member that provides an instruction to execute another control.

4. The movable body according to claim 1, wherein

the operating member is disposed on a common operation panel on which another operating member that provides an instruction to execute another control is disposed.

5. The movable body according to claim 1, wherein

the operating member is disposed closer to an ignition switch than another operating member is.

6. The movable body according to claim 1, wherein

the fuel contains hydrogen;

the fuel supply portion supplies the fuel that contains the hydrogen to the fuel cell; and

the fuel cell generates the electric power through chemical reaction between the hydrogen and oxygen.

7. A movable body comprising:

a fuel cell;

a relay portion for allowing and interrupting supply of electric power from the fuel cell;

a body that includes a space in which an occupant is housed;

a conversion portion for converting the electric power supplied from the fuel cell to driving force for driving the body;

a control portion that controls an operation of the conversion portion; and

an operating member which is disposed at a position where the operating member can be operated by the occupant housed in the body, and which provides an instruction to execute a control that allows or interrupts the supply of the electric power using the relay portion, without stopping an operation of the control portion,

wherein the operating member provides the instruction independently of an ignition switch that provides the instruction on the operation of the control portion, and

wherein the instruction to execute limit control cannot be overridden by the control portion.

8. The movable body according to claim 7, wherein

the fuel cell receives gas and generates the electric power.

9. The movable body according to claim 8, wherein

the fuel cell receives fuel gas and oxidizing gas as the gas, and generates the electric power.

10. A movable body comprising:

a fuel cell;

a fuel supply device that supplies fuel to the fuel cell;

a limit device that limits an amount of the fuel supplied by the fuel supply device;

a body that includes a space in which an occupant is housed;

a conversion device that converts electric power supplied from the fuel cell to driving force for driving the body;

a control portion that controls an operation of the conversion device; and

an operating member which is disposed at a position where the operating member can be operated by the occupant housed in the body, and which provides an instruction to execute a control that limits the amount of the supplied fuel using the limit device, without stopping an operation of the control portion,

wherein the limit device is a passage adjustment device,

wherein the operating member provides the instruction independently of an ignition switch that provides the instruction on the operation of the control portion, and

wherein the instruction to execute limit control cannot be overridden by the control portion.

11. A movable body comprising:

a fuel cell;

a relay device that allows and interrupts supply of electric power from the fuel cell;

a body that includes a space in which an occupant is housed;

a conversion device that converts the electric power supplied from the fuel cell to driving force for driving the body;

a control portion that controls an operation of the conversion device; and

an operating member which is disposed at a position where the operating member can be operated by the occupant housed in the body, and which provides an instruction to execute a control that allows or interrupts the supply of the electric power using the relay device, without stopping an operation of the control portion,

wherein the operating member provides the instruction independently of an ignition switch that provides the instruction on the operation of the control portion, and

wherein the instruction to execute limit control cannot be overridden by the control portion.
