  • Publication number: 20090256331
    Abstract: By bending and stretching a link mechanism, both left and right wheels of a vehicle can be inclined toward inside of cornering to generate a camber thrust as a lateral force, i.e. an increase in cornering force. Further, by bending and stretching the link mechanism, the passenger compartment can be inclined in accordance with inclination of a connecting link, and thus the center of gravity of the vehicle can be moved toward its inner wheel during cornering. By preventing lifting of the inner wheel during cornering, cornering performance is improved. Because the passenger compartment is inclined toward the inner wheel during cornering, centrifugal force is less likely to be felt by the occupant.

  • Patent number: 7029775
    Abstract: A fuel cell power generating apparatus (1) using a fuel cell (10) having a cathode (11) and an anode (13) disposed on opposite sides of an electrolyte membrane (12) has an air supply passage (31) through which atmospheric air is supplied to the cathode. A fuel gas supply passage (22) supplies a fuel gas such as hydrogen gas is supplied to the anode. A water spray nozzle (41) ejects liquid water onto the surface of the cathode and the sprayed water takes heat from the air around the cathode as latent heat of evaporation, which is effective to prevent dehydration of the electrolyte membrane, as well as to cool the cathode which would otherwise become overheated when the fuel cell operates continuously over a long period of time. When starting operation of the apparatus, the nozzle is made operative to eject water onto the cathode before the fuel gas is first supplied to the anode to prevent the supplied fuel gas from reacting with oxygen in air which might remain around the cathode.
