Temperature dependent protonic conductivities σ and 1H self-diffusion coefficients, D, are reported for polycrystalline hydrates of 12-tungstophosphoric acid (TPA). Conductivities were measured using ac admittance spectrometry and diffusion coefficients by the pulsed field gradient NMR technique. Co...
