Claim 0:
1. A fuel cell system comprising:
a fuel cell generator operable to generate electrical power in a stack output signal;
a rechargeable energy storage circuit;
an auxiliary load connected to the fuel cell generator, wherein the auxiliary load is powered by the rechargeable energy storage circuit while in a first mode, and powered by a local signal while in a second mode;
a first converter circuit connected to the fuel cell generator, wherein the first converter circuit is operable to convert the stack output signal into a first recharge signal while in the first mode and in the second mode, and convert the stack output signal into the local signal while in the second mode;
a first charging handle connectable to a first electric vehicle, wherein the first charging handle is operable to transfer the first recharge signal to the first electric vehicle;
a second converter circuit connected to the fuel cell generator, wherein the second converter circuit is operable to convert the stack output signal into a second recharge signal while in the first mode;
a second charging handle connectable to a second electric vehicle, wherein the second charging handle is operable to transfer the second recharge signal to the second electric vehicle; and
a switch circuit connected to the first converter circuit, the first charging handle, the second converter circuit, the second charging handle, the auxiliary load, and the rechargeable energy storage circuit, wherein the switch circuit is operable to switch the first recharge signal to the first charging handle, switch the second recharge signal to the second charging handle, and switch the local signal to the auxiliary load.
