This post will help you understand why you’d need flow fields and how to make them yourself from off-the-shelf printed circuit boards (PCBs). Table of Contents Why PCBs? Current collector and gas distribution In a PEMFC, the flow field plates generally fulfil two different purposes. One is to conduct the […]
