A fuel supply system for a fuel cell is described. One embodiment of the fuel supply system includes a fuel supply vessel; a fuel spending line in fluid communication with the fuel supply vessel and the fuel cell; a piezoelectric injector in fluid communication with the fuel spending line; and a pressure sensor connected to the fuel spending line and positioned between the fuel supply vessel and the fuel cell. A method for controlling the pressure to a fuel cell is also described.

Piezoelectric injector for fuel cell

A cryogenic fluid storage tank having a first conduit adapted for filling and extracting a cryogenic liquid from the tank and a second conduit adapted for filling and extracting a gas from the tank is disclosed, wherein heat originating from inlet and outlet conduits transferred to the tank is minimized.
