Simulation Pinpoints Root Cause of Failure

Ballard Power Systems Inc. designs, develops and manufactures zero-emission PEM fuel cell stacks.

The company is working with leading automobile manufacturers to develop the next generation of engines that are more efficient and cleaner than internal combustion engines. Engines using Ballard® fuel cells can help manufacturers reach new environmental performance levels demanded for automotive power.

The Ballard MK9 series of cell voltage monitoring (CVM) systems are electronic devices used in
automotive fuel cell stacks that monitor the voltages produced by cells during operation.

CVM chip solder joint failure can prompt a false failure signal to the vehicle control unit that subsequently can shut down the operation of the fuel cell and, possibly, the entire fuel cell engine. Improving CVM reliability means directly improving the entire fuel cell stack reliability. Therefore, addressing CVM solder joint failure is critical to improving fuel cell stack reliability.
