Which outcome occurs when a magnesium hydride battery anode corrodes unevenly?

A)Reduced hydrogen storage capacity
B)Increased electrolyte decomposition rate
C)Uniform electrode surface passivation
D)Enhanced hydride formation kinetics

💡 Explanation

Non-uniform corrosion inhibits the reversible absorption of hydrogen via destabilization of metal-hydride interface area because the **Volmer-Heyrovsky mechanism** is affected. Therefore, available sites decrease, limiting storage capacity, rather than passivating evenly, which would protect the magnesium.
