Abstract
A power generator includes a fuel container adapted to hold a hydrogen containing fuel. A two stage valve is coupled between a fuel cell and a fuel container and between a water reservoir and the fuel container. A pressure responsive actuator is coupled to the two stage valve and the fuel container.
Claims20
A power generator comprising:
- a fuel container adapted to hold a hydrogen containing fuel;
- a fuel cell;
- a water reservoir;
- a two stage valve coupled between the fuel cell and the fuel container and between the water reservoir and the fuel container;
- and
- a pressure responsive actuator coupled to the two stage valve and the fuel container, wherein the two stage valve comprises a first set of selectively mating openings that remain at least partially mated to allow hydrogen from the fuel container to reach the fuel cell, and wherein the two stage valve comprises a second set of selectively mating openings that mate in response to a differential between hydrogen pressure in the fuel container and ambient pressure.
