12. A fuel supply for a fuel cell, comprising:
-
a fuel storage area enclosed by a fuel container;
a fuel outlet disposed on the fuel container, the fuel outlet configured for coupling with the fuel cell to pass fuel from the fuel storage area to the fuel cell; and
a backpressure regulator disposed within the fuel container to cause fuel at the fuel outlet to tend to flow toward the fuel storage area when fuel is not being transferred to the fuel cell. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
