Membrane Electrode Cost at 99% usable mea share after die-cut and pinhole reject: a worked example

What does the result look like when usable mea share after die-cut and pinhole reject reaches 99%? The full calculation is worked below with real intermediate numbers. Use it during stack quoting when MEA cost dominates the bill of materials and an estimator needs a defensible MEA spend per stack before negotiating with the membrane and catalyst supplier.

The inputs for this scenario

  • Active cells per stack: 60 cells (unchanged)
  • MEA or CCM price per cell: 95 $ / cell (unchanged)
  • Usable MEA share after die-cut and pinhole reject: 99 % (raised for this scenario; the documented default is 97)
  • Fixed coating, lamination, or tooling cost per stack: 450 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable MEA cost per stack = active cells per stack × MEA price per cell × usable share) to the inputs above produces each figure below.
  • At this operating point the engine returns 6,093 $ for total mea cost per stack, the number this scenario is built around.
  • At this operating point the engine returns 102 $ / piece for mea cost per cell loaded.
  • At this operating point the engine returns 5,643 $ for variable mea cost per stack.
  • At this operating point the engine returns 450 $ for fixed coating, lamination, or tooling cost.

How this compares with the baseline

  • Against the tool's baseline example, where usable mea share after die-cut and pinhole reject sits at 97% and the headline result is 5,979 $, this scenario comes in 1.91% above the baseline at 6,093 $.
  • A figure at this level is achievable when usable mea share after die-cut and pinhole reject is genuinely sustained, not just peaked for a shift. Treating usable share as a single percentage assumes uniform loss across cells; localized pinhole clusters or edge defects on one roll can skew real cost above the model.
