Abstract
The present invention relates to methods and apparatus that can be used for efficient end-of-line (EOL) testing of electrochemical stacks once they are assembled, and prior to break-in or operation of the stack. Rapid test methods and test methods that can be performed in parallel to detect different types of defects are described. Embodiments of the methods and apparatus can be used for testing PEM fuel cell stacks and electrolyzers.
