Fuel Cell Application
The I-Scan?/sup> force and pressure measurement system is an important research and development tool for fuel cell design. In a fuel cell, numerous thin plates are stacked in close proximity to separate the flows of hydrogen or hydrocarbons and oxygen. Maintaining and improving the uniformity of the contact pressure between these plates over a large area is an important factor in the design and performance of fuel cells. Eliminating parasitic leakage paths is essential to obtaining efficient operation. I-Scan offers fuel cell manufacturers tremendous insight into the behavior of components and assembly alternatives.

Data from I-Scan allows for direct comparison of the pressure patterns from different designs thus saving time in design verification and re-engineering costs. Sensors are available in different shapes and pressure ranges, are reusable, and provide accurate pressure data. With the help of Tekscan's highly qualified sales and engineering support team, each system can be configured to meet your specific needs.
