Fuel Cell Design & Testing

Measure, view, and evaluate dynamic forces during fuel cell stack assembly.

Measurement & Analysis Of Fuel Cell Pressure Distribution

In a fuel cell, numerous thin plates are stacked in close proximity to separate the flows of hydrogen or hydrocarbons and oxygen. In addition to proper stacking pressure, applied clamping torque may also affect contact distribution within a fuel cell. A recent study, conducted by the University of Messina, Italy examines this procedure.

Challenge

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 in fuel cell stack design.

Solution

Pressure around ports and in flow field before and after pressurization.

The I-Scan™ pressure measurement system 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. Our newest sensor, the 7800 is designed to fit in around tight spaces, is trimmable on 3 sides, and has a 90 degree tab to allow for flexible electronics placement for data collection. With the help of Tekscan's highly qualified sales and engineering support team, each system can be configured to meet your specific needs.
