Latest Patents

Tsukasa Shima holds a patent for a solid electrolyte type fuel cell. This invention features a planar structure comprising multiple solid electrolyte plates, each designed with a porous cathodic layer on one side and a porous anodic layer on the other. The plates are laminated together using an interconnector plate that includes grooves for gas passages. This design allows oxidizing agent and fuel gases to be fed through the passages, reducing the length of the current path in high-resistance regions. The use of heat-resistant materials for the interconnectors, cathodes, and anodes improves oxidation resistance, durability, and overall performance. The solid electrolyte used is a Y.sub.2 O.sub.3 -containing partially stabilized zirconia, which is enhanced with 5 to 20% alumina, providing low resistance and high mechanical strength.
