Which risk increases when a fuel cell's polymer electrolyte membrane delaminates?

💡 Explanation

Delamination directly exposes electrodes to reactants which elevates risk of electrical shorts. Ion transport declines due to reduction in ionomer conductivity by the membrane, because this triggers ohmic polarization; therefore voltage degradation increases rather than catalyst surface area decline being primary.
