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.

• Which outcome predominates when ionic concentration greatly exceeds solubility limit in a solution?
• Which consequence arises when microwave signals experience multipath propagation?
• Which consequence results when highly dilute electrolyte solution?
• Which outcome occurs when the Fermi-Dirac distribution approaches absolute zero?
• Which mechanism causes elliptical galaxy shapes rather than perfect spheres?
• Which outcome occurs when applying excessive back-EMF, due to a sudden reduction in motor load, to a capacitor-shunted DC motor's circuit?
