Fuel supply system with compressed gas and liquid fuel chambers for fuel cells

摘要

Disclosed herein is a fuel supply comprising a compressed gas chamber and liquid fuel chamber. A pressure regulator connects the compressed gas chamber to the liquid fuel chamber. The pressure regulator is capable of taking a high pressure input from the compressed gas chamber and providing a substantially constant lower output pressure to the liquid fuel chamber. The pressure of the compressed gas chamber can decrease over time, but the pressure that urges liquid fuel out of the liquid fuel chamber remains substantially at the same level.

主权项

1. A fuel supply system comprising
a compressed gas chamber, a first valve comprising an inner center post and an outer center post concentrically disposed around the inner center post so as to leave a space between the inner center post and the outer center post, and a sealing member disposed in the space, a liquid fuel chamber, wherein a pressure regulator connects the compressed gas chamber to the liquid fuel chamber, wherein the pressure regulator is capable of taking a pressure input from the compressed gas chamber and providing a output pressure to the liquid fuel chamber to urge a liquid fuel out of the liquid fuel chamber and wherein the pressure input is higher than the output pressure, and wherein gas from the compressed gas chamber is transported through the first valve to the pressure regulator and back through the first valve to the liquid fuel chamber.
