Highlights
- An elementary reaction model for ammonia protonic ceramic fuel cells
was proposed.
- Complex ammonia decomposition/electrochemical reaction steps were
deconvoluted.
- The ammonia-hydrogen performance ratio reaches 95% by accelerating
ammonia decomposition at anode.
- Anode parameters affect cell performance by affecting the ammonia
decomposition and charge transfer reaction.
- Strategies for the subsequent design of ammonia protonic ceramic fuel
cells were proposed.
