Abstract
A method, computer program product, and bipolar plate structure for a fuel cell stack inside a polymer-electrolyte-membrane (PEM) fuel cell stack. The bipolar plate structure may be created, wherein creating the bipolar plate structure may include forming a z-shaped pattern for a plurality of hydrogen flow channels. Creating the bipolar plate structure may include forming a z-shaped pattern for a plurality of air flow channels. Creating the bipolar plate structure may include forming an x-shaped crossing pattern for a plurality of coolant flow channels.
