Thermal coefficient (α = ∂V/∂T) of redox potential (V) of electrodes is a intrinsic parameter of the redox reaction. Electrodes with high-α are useful for us to convert thermal energy into electricity. We evaluated α in three kinds of Prussian blue analogues as a function of sodium concentration (x). Furthermore, α(x) was calculated with use of point charge model, which qualitatively reproduced α(x) obtained by our experiment.
