Which process limits the achievable efficiency in a solid oxide fuel cell operating at high temperature?

💡 Explanation

At high fuel utilization Nernst potential decrease occurs because the fuel concentration at the anode is significantly lowered, which reduces the cell voltage and, consequently, the efficiency. Therefore Nernst potential reduction results, rather than segregation, activation energy increase, or shorting which involve other failure mechanisms.
