摘要： The present invention aims to provide a membrane electrode assembly that can increase durability by increasing the strength of an extending part of a solid polymer electrolyte membrane, and can also reduce cost by minimizing the volume of the solid polymer electrolyte membrane used.In the present invention, an anode electrode is provided on one side of a solid polymer electrolyte membrane, and a cathode electrode is provided on the other side of the solid polymer electrolyte membrane. The solid polymer electrolyte membrane is formed such that its outer peripheral portion extends the anode electrode and the cathode electrode on both sides thereof. A framc-shaped first sealing member is closely contacted with the outer peripheral edge face of the anode electrode or the cathode electrode. The frame-shaped first sealing member coats and supports one face of the extending part of the solid polymer electrolyte membrane.

摘要： An electrode structure having a pair of electrode catalyst layers and a polymer electrolyte membrane held between both the electrode catalyst layers is provided. The polymer electrolyte membrane is a sulfonate of a hydrocarbon-based polymer comprising a main chain in which two or more benzene rings are bound together directly or through a divalent group. The membrane includes 5% or more by weight of water coordinated to protons of sulfonic acid groups. The polymer electrolyte membrane may include a fluorine-containing ion conducting polymer such that the ratio of fluorine content in the polymer electrolyte membrane to the fluorine content in the electrode catalyst layers is in the range of from 0.2 to 2.0. The electrode structure constitutes a fuel cell, which generates power when oxidizing gas is supplied to the one side of the electrode structure and reducing gas to the other side.

摘要： An NOx sensor for an exhaust gas is made from .beta.-Nb.sub.2 O.sub.5 as a primary component and TiO.sub.2 as a subsidiary component. The TiO.sub.2 content is in a range of 0.1% by weight .ltoreq.TiO.sub.2 .ltoreq. 20% by weight. In place of TiO.sub.2, Ru may be used in the NOx sensor. The Ru content is in a range of 0.1% by weight .ltoreq.Ru.ltoreq. 10% by weight. Thus, the NOx sensor has an excellent NOx adsorbing ability and is higher in sensitivity to NOx in an exhaust gas.
