← ScienceWhich outcome increases when fuel cell water freezes?
A)Electrolyte membrane rupture✓
B)Hydrogen gas over-production
C)Catalyst surface area increase
D)Voltage output stabilization
💡 Explanation
Fuel cell water freezing causes volume increases. Ice forming exerts pressure, resulting in electrolyte membrane rupture because water's solid phase is less dense; therefore cells fail, rather than hydrogen exploding or catalyst improving which needs high temperatures.
