Which outcome occurs when an ammonia fuel cell is internally cooled via recirculated hydrogen gas?

💡 Explanation

Thermal runaway is mitigated because the recirculated, cooled hydrogen gas facilitates *convective heat transfer* away from hot spots. Therefore, localized exothermic reactions are arrested, and thermal runaway spread slows, rather than accelerating via conductive heating.
