I’m keen to hear where this goes! So it sounds like you are going down the chemistry path? I feel like you could try building a model system, I know with hydrogen fuel cells they are trying to find a catalyst other then platinum because it is expensive and only a limited supply of it. Not sure if this interests you? I also think trying to learn from mitochondria and seeing how you can apply this to fuel cells could be a fun interdisciplinary approach, what subjects are you taking?
