The neutron diffraction of BaZr $_{0.8}$ Sc $_{0.2}$ O $_{2.9}$ with and without proton were measured and analyzed by Rietveld method and Maximum Entropy Method. We found that the location of proton is 12 site near oxygen ion. The heat capacity of sample with proton is larger than that without proton. This difference is discussed in term of the changes of the crystal structure and lattice vibrations due to the dissolution of proton.
