Abstract
Official abstract text for this publication.
Passive temperature supervision devices for detecting temperature changes in compressed gaseous fuel storage systems of fuel cell systems. More specifically, systems and methods for detecting temperature changes in compressed gaseous fuel storage systems such as compressed gaseous fuel tanks of motor vehicles, where increases and decreases in temperature can be detected without the need for electric supervision systems.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for detecting a temperature change in a compressed gaseous fuel storage system of a fuel cell system comprising: a temperature-sensing circuit cooperatively coupled to a compressed gas tank of the compressed gaseous fuel storage system; a passive temperature supervision device coupled to the compressed gas tank and the circuit and configured to passively detect the change in an internal temperature of the compressed gas tank by an irreversible cha…
