This is because the weight balance of the fuel cell two-wheeled vehicle 10 is considered in combination with the arrangement positions of the VCU 54 and the PDU 56.

  By the way, the temperature of the fuel cell 50 needs to be controlled during its operation. This is because an electrochemical reaction between hydrogen and oxygen is performed under optimum conditions. Therefore, a pump 78 is provided between the main frame 26 and the underframe 28 to supply a cooling medium to the fuel cell 50, and is connected to the fuel cell 50 through a piping system (not shown).

Similarly to the third support frames 35, 35, the first holding ring 82, the second holding ring 90, and the third holding ring 98 are fixed to the pair of second support frames 33, 33.

  The first holding ring 82, the second holding ring 90, and the third holding ring 98 have a first hydrogen cylinder 200 and a second hydrogen cylinder 202 for storing high-pressure hydrogen gas filled from the hydrogen filling port 74. And a third hydrogen cylinder 204 is attached. That is, by loosening the bolts 88, 96, and 104, the movable half rings 84b, 92b, and 100b are opened through the hinge members 86, 94, and 102, and the first to third hydrogen cylinders 200, 202, and 204 are After mounting on the fixed half rings 84a, 92a, 100a, the movable half rings 84b, 92b, 100b are opened via the hinge members 86, 94, 100, and the bolts 88, 96, 104 are again screwed. To do. As a result, the first to third hydrogen cylinders 200, 202, and 204 are firmly fixed. In this case, the first hydrogen cylinder 200 is formed to have a shorter length in the longitudinal direction than the second hydrogen cylinder 202 and the third hydrogen cylinder 204, and the diameter thereof is also the second hydrogen cylinder 202, The diameter is smaller than that of the third hydrogen cylinder 204. Accordingly, one end portion of the first hydrogen cylinder 200 extends to the front surface of the fuel cell 50 and does not come into contact with the first hydrogen cylinder 200 and is in an unreached state. One end of the second hydrogen cylinder 202 and the third hydrogen cylinder 204 extends to below the support plate 46 that supports the fuel cell 50.

  In the figure, reference numeral 250 denotes an air cleaner used for supplying clean air to the fuel cell 50 via the supercharger 70.

  The fuel cell two-wheeled vehicle 10 incorporating the hydrogen cylinder mounting structure according to the present embodiment is basically configured as described above. Next, the function and effect will be described.

  When the fuel cell motorcycle 10 is started in a state where the first hydrogen cylinder 200, the second hydrogen cylinder 202, and the third hydrogen cylinder 204 are sufficiently filled through the hydrogen filling port 74, the air cleaner 250 cleans. While the converted air is supplied to the fuel cell 50 through the supercharger 70, fuel is supplied to the fuel cell 50 from any one of the first hydrogen cylinder 200 to the third hydrogen cylinder 204, or a plurality of them. Hydrogen gas as gas is supplied. In this case, the hydrogen gas outlets of the first hydrogen cylinder 200 to the third hydrogen cylinder 204 are decompressed to a predetermined pressure via the hydrogen gas supply systems 66a to 66c including the first to third regulators. be introduced. In the fuel cell 50, oxygen contained in the air introduced from the air cleaner 250 and low-pressure hydrogen gas supplied from any of the first hydrogen cylinder 200 to the third hydrogen cylinder 204 are electrochemically supplied. In response, a predetermined direct current is taken out and supplied to the power unit 62.

  When a driver (not shown) operates the steering handle 20 to start the travel of the fuel cell two-wheeled vehicle 10, the generated water generated when the fuel cell 50 reacts electrochemically is generated in the generated water discharge section. Hydrogen gas discharged from 76 to the outside and excessively supplied to the electrochemical reaction is discharged from the discharge port 300 to the outside through the emergency release valve 68 as necessary. Since the generated water is discharged to the generated water discharge unit 76 through the inside of the power unit 62, when the generated water that is being discharged freezes, the motor coil constituting the power unit 62 is heated to generate heat. Can be thawed. For example, at the time of starting, when it is determined that the generated water in the discharge road is frozen, power can be transmitted to only a part of the coils of the motor to generate heat so that the fuel cell motorcycle 10 does not start. Judgment of freezing is made based on whether or not the pressure in the fuel cell 50 at the time of starting is higher than a predetermined value. The VCU 54 and the PDU 56 achieve their respective control functions and drive functions during traveling. In order to supply the cooling medium to the fuel cell 50, the pump 78 circulates a necessary refrigerant with a predetermined temperature as a threshold value. As described above, the electric power obtained by the fuel cell 50 is supplied to the power unit 62 to control the energization of the drive motor, and the secondary batteries 80 and 80 have surplus electric power for the driving action or the brake system 24. It functions to store regenerative electric power generated by performing a braking operation using.

  Therefore, in the present embodiment, the first hydrogen cylinder 200 to the third hydrogen cylinder 204 are held by the second support frames 33 and 33 and the third support frames 35 and 35. Then, in relation to the fourth support frames 33 and 33 and the third support frames 35 and 35, a first holding ring 82 as a fastening means adapted to the outer peripheral diameter of the first hydrogen cylinder 200 to the third hydrogen cylinder 204. The second holding ring 90 and the third holding ring 98 are disposed so as to be openable and closable. The first holding ring 82, the second holding ring 90, and the third holding ring 98 allow the first hydrogen cylinder 200 to the third hydrogen cylinder 200 to third. The hydrogen cylinder 204 is configured so that it can be sufficiently held not only when stopped but also during traveling. In addition, at the boundary portion between the second hydrogen cylinder 202 and the third hydrogen cylinder 204, the first hydrogen cylinder 200 is held above and the soot is also stacked, and these hydrogen cylinders 200, 202 and 204 are fixed. Yes.

  And the footrest part 210a, 210b for mounting a driver | operator's right and left leg was provided in the upper surface of the 1st hydrogen cylinder 200 and the 2nd hydrogen cylinder 202. As shown in FIG. Since the relatively heavy second hydrogen cylinder 202 and the third hydrogen cylinder 204 are provided in the lower part of the vehicle main body of the fuel cell two-wheeled vehicle 10, the center of gravity can be lowered because their arrangement positions are low. In addition, since the first hydrogen cylinder 200 smaller in diameter than the second hydrogen cylinder 202 and the third hydrogen cylinder 204 is disposed above the boundary portion between the second hydrogen cylinder 202 and the third hydrogen cylinder 204, the operation is performed. Both the legs of the person can be placed on the footrests 210a and 210b on the left and right sides of the first hydrogen cylinder 200. Thereby, the advantage that the driver's foot straddle improves is obtained.

  Of course, during running, the first hydrogen cylinder 200, the second hydrogen cylinder 202, and the third hydrogen cylinder 204 are not opened at the same time, and after the hydrogen gas in the second hydrogen cylinder 202 is exhausted, the third hydrogen cylinder is exhausted. The hydrogen gas supply system 204 supplies the hydrogen gas 204 to the fuel cell 50 and supplies the hydrogen gas from the first hydrogen cylinder 200 to the fuel cell 50 after the third hydrogen cylinder 204 is used up. By controlling 66a to 66c, sufficient hydrogen gas necessary for long-distance traveling can be stored in these hydrogen cylinders 200, 202, and 204. Furthermore, if the hydrogen gas in the second hydrogen cylinder 202 and the third hydrogen cylinder 204 is controlled so that the hydrogen gas is always used, the hydrogen gas in these hydrogen cylinders 202 and 204 should be interrupted for the first time. There is an advantage that the hydrogen gas of the first hydrogen cylinder 200 can be used for emergency.

  Further, according to the present embodiment, the length of the first hydrogen cylinder 200 is made shorter than the lengths of the second hydrogen cylinder 202 and the third hydrogen cylinder 204 in the longitudinal direction, and the front of the fuel cell 50 is further forward. In the second hydrogen cylinder 202 and the third hydrogen cylinder 204, the ends of the second hydrogen cylinder 202 and the third hydrogen cylinder 204 wrap around the support plate 46. For example, the first hydrogen cylinder 200 used as an auxiliary can achieve the effect of downsizing without increasing the length of the fuel cell two-wheeled vehicle 10 in the longitudinal direction of the vehicle, and the weight balance is also good. That is, by arranging the first hydrogen cylinder 200 between the second hydrogen cylinder 202 and the third hydrogen cylinder 204, the first hydrogen cylinder 200 is located at the center of the vehicle, so that the weight balance can be improved. it can.

  In addition, the fuel cell 50 is disposed in a state where it stands up perpendicular to the longitudinal directions of the first hydrogen cylinder 200, the second hydrogen cylinder 202, and the third hydrogen cylinder 204. This also has an advantage that the length of the fuel cell two-wheeled vehicle 10 itself can be further shortened because the relatively long fuel cell 50 is oriented in the vertical direction. In addition, since the fuel cell 50 is disposed below the seat on which the driver is seated (see the two-dot chain line in FIGS. 4 and 5) and is located at the center of the fuel cell motorcycle 10, the fuel cell motorcycle 10 Excellent balance in the front-rear direction and left-right balance. Further, the first hydrogen cylinder 200, the second hydrogen cylinder 202, and the third hydrogen cylinder 204 have the first holding ring 82, the second holding ring 90, and the third holding ring 98 that can be freely opened and closed. Since the first to third hydrogen cylinders 200, 202, and 204 can be sufficiently held by the bolts 88, 96, and 104, stability can be increased and maintenance can be facilitated. That is, the first to third hydrogen cylinders 200, 202, and 204 can be easily attached and detached by removing the bolts 88, 96, and 104 of the first holding ring 82, the second holding ring 90, and the third holding ring 98, respectively. Therefore, the advantage of excellent maintainability can be obtained.

  The present invention has been described in detail with reference to the preferred embodiment. However, the present invention is not limited to this embodiment, and various modifications can be made without departing from the scope of the present invention. Needless to say.
