An air pump 143 that supplies air containing oxygen to the fuel cell is provided below the seat 15. Further, the front end portion of the rear arm 17 is supported on the body frame, and the rear end portion thereof is swingable up and down. A rear wheel 19 as a drive wheel is rotatably supported at the rear end.

  In addition, the space surrounded by the vehicle body frame in which the fuel cell 100 is disposed below the foot portion 22 where the passenger in the space surrounded by the vehicle body frame places his / her foot is, for example, the vehicle body frame horizontally When a plurality of bars (such as pipes) arranged in the direction are included, the space is above or below the surface formed by connecting the ends of the bars. Moreover, when the upper end part and lower end part of the said surface are clear, it is good also as a space between the said upper end part and lower end part further limiting. For example, when the vehicle body frame includes three bars, a space surrounded by the three bars may be used. Further, when the body frame itself forms a section, for example, in the case of a monocoque frame, the inner space may be a space surrounded by the body frame.

  In the straddle-type vehicle 1 equipped with a fuel cell, the fuel cell 100 is disposed substantially at the center of the vehicle body frame. On the other hand, an electric motor, a motor controller, and a drive mechanism (both not shown) are provided in the rear arm 17, and the motor controller supplies electric energy generated in the fuel cell 100 to the electric motor to rotate the electric motor. Then, the driving mechanism transmits the rotational force of the electric motor to the rear wheel 19 so that the fuel cell-equipped straddle-type vehicle travels.

  The fuel cell 100 is covered with an arc-shaped upper cover 21 from above to the vicinity of the handle. A leg shield (mudguard) 23 for protecting a passenger's foot is attached to the front portion of the upper cover 21, and the bottom portion of the arc-shaped upper cover 21 serves as the foot portion 22, and the lower side of the foot portion 22. A fuel cell 100 is provided.

  A left cover 25 and a right cover 27 are connected to both end surfaces of the upper cover 21. Both the left cover 25 and the right cover 27 are made of a transparent member so that the fuel cell 100 can be visually recognized. A lower cover 29 is connected to both the left cover 25 and the right cover 27. The lower cover 29 is cut out so that the rear arm 17 protrudes. A front end portion of the lower cover 29 extends to above the front wheel 7 to constitute a front carrier 31. Further, the rear end portion of the lower cover 29 extends to above the rear wheel 19 to constitute a rear carrier 33.

  The vehicle body frame has a down tube 104 extending between the lower cover 29 and the upper cover 21 so as to rise from the vicinity of the fuel cell 100 to the upper side of the front fork 5. A pipe 106 is attached, and a steering shaft having a handle 3 fixed to the upper end is rotatably inserted and supported in the head pipe 106.

  In the saddle-ride type vehicle 1 equipped with the fuel cell, a front cover 35 is provided from the front carrier 31 to the headlamp 11. The front cover 35 is continuous with both the left cover 25 and the right cover 27.

  Next, the configuration of the fuel cell 100 will be described with reference to FIG. The fuel cell 100 is a direct methanol fuel cell system, and includes a fuel cell stack 101 in which unit cells each having an electrolyte sandwiched between an anode electrode and a cathode electrode are stacked. The electric energy generated in the fuel cell stack 101 is transmitted to the secondary battery 102 through the electric wiring 1010 and stored.

  In the fuel cell 100, a fuel pump 107 communicates with the fuel tank 103 via a pipe, and the fuel pump 107 communicates with the aqueous solution 109 via a pipe (not shown). The fuel tank 103 is attachable and detachable so that the fuel is supplied from the fuel cartridge 200 filled with high-concentration (about 50%) liquid methanol (referred to as fuel). . Specifically, a fuel cartridge holder 220 is provided in the fuel tank 103, and the fuel cartridge holder 220 holds the fuel cartridge 200 in a detachable manner. With this configuration, the fuel cell-equipped straddle-type vehicle 1 does not require complicated fuel piping and does not require fuel supply at a supply station. A fuel supply port may be provided in the fuel tank 103 so that fuel can be supplied from other than the fuel cartridge 200.

  The aqueous solution tank 109 includes a water supply port (not shown). The aqueous solution tank 109 is communicated with a radiator 115 having an electric fan 113 through a pipe 111. The radiator 115 is communicated with the radiator 119 via a pipe 117. The radiator 119 is communicated with the aqueous solution pump 123 via the pipe 121. The aqueous solution pump 123 is communicated with the filter 129 through the pipe 125 and the pipe 127. The filter 129 communicates with the anode side of the fuel cell stack 101 via the pipe 131.

  On the other hand, the air filter 141 and the air pump 143 are communicated with each other through a pipe, and the air pump 143 is communicated with the cathode side of the fuel cell stack 101 via the pipe 145.

  The fuel cell stack 101 communicates with the aqueous solution tank 109 via a pipe hidden in the pipe 145 in the figure. The fuel cell stack 101 communicates with the radiator 153 through the pipe 151. The radiator 153 communicates with a water tank 159 provided with a drain 157 via a pipe 155. The water tank 159 is communicated with the water pump 163 via the pipe 161, and the water pump 163 is communicated with the aqueous solution tank 109 via the pipe 105. The aqueous solution tank 109 and the water tank 159 are connected via a pipe 167.

  Next, the operation of the fuel cell 100 will be described. The fuel cartridge 200 is attached to the fuel cartridge holder 220 to supply fuel to the fuel tank 103. Further, water is supplied to the aqueous solution tank 109. Then, the fuel pump 107, the aqueous solution pump 123, and the water pump 163 are driven. The fuel pump 107 supplies fuel from the fuel tank 103 to the aqueous solution tank 109, and about 3% methanol aqueous solution is generated in the aqueous solution tank 109.

  By driving the aqueous solution pump 123, the aqueous methanol solution in the aqueous solution tank 109 is purified by the filter 129 and supplied to the anode side of the fuel cell stack 101. At this time, the radiators 115 and 119 cool the aqueous methanol solution, and the temperature thereof becomes 60 to 70 degrees by adjusting the rotation speed of the electric fan 113. On the other hand, by driving the air pump 143, the air filter 141 purifies the surrounding air, and the purified air is supplied to the cathode side of the fuel cell stack 101.

  On the anode side of the fuel cell stack 101, methanol and water in an aqueous methanol solution undergo an electrochemical reaction to generate carbon dioxide and hydrogen ions, and the generated hydrogen ions flow into the cathode side of the unit cell. The hydrogen ions electrochemically react with oxygen in the air supplied to the cathode side to generate water vapor and electric energy, and the generated electric energy is supplied to the secondary battery 102 and stored.

  Carbon dioxide generated on the anode side of the fuel cell stack 101 passes through the pipe 167 and the water tank 159 from the aqueous solution tank 109 and is discharged from the drain 157. On the other hand, water vapor generated on the cathode side of the fuel cell stack 101 is gas-liquid separated by a radiator 153 which is a gas-liquid separator. The dry air generated by this gas-liquid separation passes through the water tank 159 and is discharged from the drain 157. Further, water generated by the gas-liquid separation is collected in the water tank 159 and supplied to the aqueous solution tank 109 by the driving force of the water pump 163.

  Unlike the radiators 115 and 119 for controlling the temperature of the liquid, the radiator 153 is a component intended to separate water vapor into more air and water. In the saddle-ride type vehicle 1 equipped with the fuel cell, the radiator 153 is disposed in the rear carrier 33 located behind the space surrounded by the vehicle body frame, so that the gas-liquid separation capability is reduced due to heat generated by the fuel cell stack 101 and the like. Can be prevented. Further, since there are no parts around the rear carrier 33, a large amount of traveling air can be applied, and gas-liquid separation can be further promoted. In addition, gas-liquid separation can be promoted by heat escape from the rear carrier 33. Moreover, since parts other than the radiator fin of the radiator 153 are made of stainless steel, high strength can be obtained.

  If the rear carrier 33 and the radiator 153 are integrated, the heat of the radiator 153 escapes to the rear carrier 33, so that gas-liquid separation can be further promoted. In addition, structural materials can be reduced by integration, thereby reducing weight and cost.

  The fuel cell 100 generates power even when the vehicle is stopped. At that time, the gas and liquid cannot be separated by the traveling wind. However, since there is a space between the rear carrier 33 and the rear wheel 19, a large amount is generated during the stop. Natural convection can be applied to the radiator 153, and gas-liquid separation can be promoted. Further, since the radiator 153 is disposed in the rear carrier 33, the radiator 153 can be protected by the rear carrier 33 when an unexpected external force is applied.

  In the straddle-type vehicle equipped with the fuel cell according to the first embodiment configured and operated as described above, the fuel cell 100 is provided below the foot portion 22, and the secondary battery 102 is provided in the middle of the down tube 104. The air pump 143 is provided below the seat 15. If only three components including the fuel cell 100, the secondary battery, and the sheet 15 are extracted, they can be shown as shown in FIG.
