Fujifilm Prescale lets you Picture the Pressure® in your fuel cell process by helping you select, use, and analyze results from your fuel cells.
A fuel cell stack consists of multiple single cells laminated together. In its operating state, a clamp load is applied to the stack by tightening the end plates using the bottles. If the clamp load is too low, contact resistance will increase, resulting in lower power generation efficiency and even fuel leaks. On the other hand, if the clamp load is too high, the fuel cell seal will deteriorate quickly. Although there are many ways to ensure the load on an entire cell stack, a pressure indicating film such as Prescale is the only way to measure the load distribution on an individual cell.
Prescale is a quick and easy way to check distribution or uniformity of contact pressure. Simply place the pressure indicating film between two mating or contacting surfaces and apply pressure as normally required. The film instantly changes color. The variation in the red color density can be compared with a color chart to determine the pressure. In addition, the color will give an immediate footprint of the area. Any imperfections or variations along the contact area can be spotted with a quick check. There are seven ranges from 7 psi to 43,200 psi, and digital analysis is also available.
