Metrology for fuel cells

Different functional layers come together in a fuel cell stack  – i.e. a unit consisting of many individual fuel cells connected in series: Bipolar plates, gas diffusion layers and catalytically coated membranes. The membrane electrode assembly (MEA) only works reliably and at full power when these components are precisely manufactured and optimally matched to each other. To ensure this performance, precise testing and measuring procedures are essential throughout the entire manufacturing process.
