Abstract

A pressurized gas storage system includes an outer shell having an inner and outer surface. The inner surface defines an inner volume for holding a pressurized gas. A first electrically conductive layer is attached to the outer shell. An inner liner is disposed over the inner surface. A second electrically conductive layer is attached to the inner liner. A capacitance meter measures the capacitance between the first and second electrically conductive layers wherein a change in capacitance indicates buckling in the storage system.

Description

technical field [0001] The present invention relates to a gas storage system for detecting liner buckling for fuel cell powered vehicles. Background technique [0002] Fuel cells are used as a source of electrical power in many applications. In particular, it is proposed to use fuel cells in automobiles to replace internal combustion engines. Commonly used fuel cell designs use solid polymer electrolyte ("SPE") membranes or proton exchange membranes ("PEEM") to provide ion transport between the anode and cathode. In proton exchange membrane type fuel cells, hydrogen is supplied to the anode as fuel and oxygen is supplied to the cathode as oxidant. Oxygen can be in a pure state (O 2 ) or air (O 2 and N 2 mixture). Typically a PEM fuel cell has a membrane electrode assembly ("MEA") in which a solid polymer electrolyte has an anode catalyst on one surface and a cathode catalyst on the opposite surface. [0003] Modern fuel cell vehicles store hydrogen in pressure vessels...
