| Abstract: |
A power supply system for enhancing the economic viability of different modes of transportation that incorporate fuel cells to generate electricity. For example, the power supply system of the present invention provides for the off-board use of the electric power generated by an on-board power plant, such as a fuel cell, of a mobile vehicle power system, such as an electric car. Off-board use, or use remote from the vehicle, of the electrical power includes the delivery of power to a remote site. Off-board stations are provided for delivery of fuel to the vehicle and/or for receiving the electrical power generated by the fuel cell. The off-board station and the vehicle are appropriately equipped for quick and easy interconnection such that electrical power is drawn from the fuel cell for off-board use.

Having described the invention, what is claimed as new and desired to be secured by Letters Patent is:
1. A power system for converting fuel to electricity, comprising a mobile vehicle power system and an off-board station, the mobile vehicle power system including
- a rechargeable battery,
- motor means coupled to said battery for propelling the vehicle,
- a power plant for converting fuel to electrical power and for connection to said battery to recharge said battery,
- storage means for storing fuel for said power plant, and
- means for coupling to said off-board station for delivering thereto electrical power generated by said power plant when not required for on-board use,
and said off-board station including
- means for receiving electrical power from said mobile vehicle power system,
- output means for providing at least a portion of said electrical power for use off-board of said mobile vehicle power system, and
- means for delivering fuel to said mobile vehicle power system, and said mobile vehicle power system includes means for receiving fuel from said off-board station for provision to said power plant.
