Gas temperature moderation within compressed gas vessel through heat exchanger

Abstract

A pressure vessel for storing fuel cell reactants is disclosed. The pressure vessel includes an inner shell formed from a moldable material and forming a cavity therein, and an outer shell formed about the inner shell. A heat transfer member is disposed within the vessel cavity. The heat transfer member is thermally coupled a suitable external thermal mass external the pressure vessel to minimize the effect of thermal energy on the vessel. The heat transfer member may be a metallic structure within the cavity, or may be integrated within the inner shell on an inner shell surface. The external thermal mass may further be thermally coupled to either an active or a passive external thermal handling system for controlling the temperature of the fluid within the vessel.
