Pressurex Zero® Fuel Cells Application

Pressurex® reveals pressure distribution and magnitude in a fuel cell. Different ranges of pressure film are available

Sensor Products Inc. announces Pressurex Zero®, the newest addition to its tactile pressure-indicating sensor films. Pressurex Zero® characterizes tactile contact surface pressure down to an extremely low 7.2 PSI (0.5 kg/cm²). It is an easy-to-use flexible film that is placed between contacting or mating surfaces to instantly and accurately measure and map pressure magnitude and distribution. Variations in contact surface pressure are immediately visible by the impression made on the film. The range for Pressurex Zero® is 7.2 28 PSI (0.5 1.97 kg/cm²).

Engineers in the Fuel Cell Industry are among those who spurred the development of this extremely low pressure range. Several other ranges of low pressure film from Sensor Products are currently used in the Fuel Cell industry. Pressurex® aids in the design, manufacture and testing of fuel cells by helping to ensure uniform and accurate spacing between membranes in order to achieve maximum current flow and fuel usage efficiency in a fuel cell stack assembly. Engineers involved in the research design and testing of fuel cells for aerospace, airplanes, cars, electronic devices, military applications, stationery power installations, mobile phones, laptop computers and personal electronics, among other uses, should be interested in this development.

Pressurex® comes in the form of a thin clear plastic sheet (4 or 8 mil), physically similar in appearance to paper and is available in eight different pressure ranges. When placed between contacting surfaces, the film instantaneously and permanently changes color directly proportional to the actual pressure applied. The precise pressure magnitude (PSI or kg/cm²) is easily determined by comparing color variation results to a color correlation chart (conceptually similar to interpreting Litmus paper).
