Which outcome increases within solid-oxide fuel cell electrolytes at intermediate temperatures?

💡 Explanation

When temperature is intermediate, grain boundary ionic conductivity enhancement occurs because thermal energy increases ion mobility along the interfaces while bulk conductivity is still limited, enhancing overall ionic transport. Therefore, grain boundary ionic conductivity increases, rather than electronic conduction, decomposition, or poisoning which require different temperature ranges or chemistries.
