"the cell was firstly operated at an electrolysis mode with a constant current density of 0.6 A cm−2 for three minutes to generate hydrogen, which was instantly consumed by switching to a fuel cell mode at 0.2 A cm−2 for two minutes"
So, 22% round trip efficiency
- rrmm 6y agoShouldn't you take into account the voltage. From the graphs they don't look like they were symmetrical.
- tln 6y agoDoh! Fig 6c[0] shows ~1.6 in and 0.4v out so... 5% round trip efficiency? [0] https://www.nature.com/articles/s41467-020-15677-z/figures/6 https://www.nature.com/articles/s41467-020-15677-z/figures/6
