I have developed teaching materials using fuel cell and superconductor for the experimental science study of primary and junior high school. As for the teaching materials of superconductor, I have successfully synthesized melt-processed oxide superconductor. The maximum efficiency of the material such as diameter, weight, fishing power and magnetic rise height was 36mm, 50g, 1.9N and 13mm, respectively. Using materials, fishing experiment of earth balloon (total weight 250g) was succeeded. The demonstration of melt-processed superconductor has operated on 13 March 2010. An audience was mainly primary and junior high school students. As for the development of teaching materials using solid oxide fuel cell, I have succeeded to prepare Ni+YSZ porous anode substrate which can use teaching materials.
