Fuel cell stack assembly design

PressurexR reveals the pressure distribution and magnitude between any two contacting surfaces. PressurexR is a thin sensor film that is actually placed between the two contacting surfaces. Surface pressure distribution and magnitude are instantaneously and permanently captured by virtue of a color change of the sensor film. Similar in philosophy to Litmus paper, the color PressurexR turns is directly proportional to the amount of force applied.
