A typical PEMFC stack for an automotive application requires 600–800 half-BPPs, which potentially cause extensive wear on forming tools over millions of forming cycles. This study introduces a finite element-based simulation framework incorporating the Archard wear model to predict tool wear patterns and degrees. By iteratively updating tool geometries based on contact pressure and sliding distance, the model identifies maximum wear near tool radii. Experimental validation using a tool wear test bench confirms its predictive accuracy.enPEMFuel cellMetallic bipolar plateTool wearNumerical simulation600 Technik, Medizin, angewandte Wissenschaften::620 Ingenieurwissenschaftenpresentation
