Heated outlet valve for a hydrogen storage tank

摘要

A compressed gas storage tank that has particular application for storing hydrogen for a fuel cell system. The compressed gas tank includes a cylindrical adapter and valve through which the hydrogen is removed from the tank. A low cost generator is positioned in the tank and has a rotating element positioned in a channel extending through the adapter. As hydrogen is removed from the tank, the mass flow of the hydrogen causes the rotating element to rotate which causes the generator to generate electricity. One or more resistive heating element are positioned in the adapter, preferably proximate to tank seals, that receive an electrical current from the generator that heats the resistive heating element and the adapter to increase the temperature of the adapter and the hydrogen being removed from the tank.
