📊 Limiting Current (Cowan-Brown LCD Determination, Preventing Water Splitting & pH Swing)

EDR Limiting Current Density (LCD) Calculator

Determine Limiting Current Density ($LCD ext{ in mA/cm}^2$) using Cowan-Brown resistance inflection plots: operate stacks safely below critical LCD thresholds ($I_{op} < 0.80 ext{ }LCD$), prevent catastrophic water dissociation splitting ($H_2O ightarrow H^+ + OH^-$) and severe localized pH precipitation, and membrane yields.
