Some fuel cell systems are already on the market. One of them is Solid Polymer Fuel Cell (SPFC) which uses a polymer as electrolyte. This operates under 100\u2103 and therefore expensive noble metal catalyst is required to accelerate the reaction. The other one is Solid Oxide Fuel Cell (SOFC) which typically uses an yttria-stabilized zirconia (YSZ) as electrolyte. This system operates at 800-1000\u2103 to keep O<sup>2-<\/sup> ions mobile in the electrolyte and therefore the whole system has to be heat-resistant, which is one reason the system is very expensive and keep it from being popular.<\/p>\n<p>The intermediate-temperature fuel cell works at 250-500 \u2103 and is the literally \u201cintermediate system\u201d which does not need either noble metal catalyst or heat-resistant structure. It is expected as the next-generation system and would be cheaper than the present ones. Then, why this system is not realized now? Just because there is no ion conductor in which either H<sup>+<\/sup> or O<sup>-2<\/sup> is mobile enough at the intermediate temperature.<\/p>\n<p>In our lab, we are developing the solid state electrolyte which is ion-conductive and suitable for intermediate-temperature fuel cell. Until now, we developed the novel process itself to inject H<sup>+<\/sup> ions into glass electrolyte in extremely high concentration (10-20mol\uff65L<sup>-1<\/sup>) and realized the world-highest-level proton-conductive glass. In the present, we are improving this glass electrolytes and developing the electrode materials suitable for them.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-239 aligncenter\" src=\"https:\/\/www2.tagen.tohoku.ac.jp\/lab\/omata\/wp-content\/uploads\/sites\/90\/fuelcell-300x283.jpg\" alt=\"fuelcell\" width=\"300\" height=\"283\" srcset=\"https:\/\/www2.tagen.tohoku.ac.jp\/lab\/omata\/wp-content\/uploads\/sites\/90\/fuelcell-300x283.jpg 300w, https:\/\/www2.tagen.tohoku.ac.jp\/lab\/omata\/wp-content\/uploads\/sites\/90\/fuelcell.jpg 585w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<ul>\n<li><a href=\"http:\/\/dx.doi.org\/10.1149\/2.093311jes\">Electrochem.
