The present invention provides a magnetic field measuring device comprising first to fourth magnetoelectric transducers, magnetic convergence plates, and a calculation unit that calculates the strength of a magnetic field applied in a horizontal direction and/or a vertical direction with respect to a magneto-sensing surface of the magnetoelectric transducers, wherein the magnetic convergence plates are placed in the vicinity of the first to fourth magnetoelectric transducers so as to convert magnetic field vectors, and the calculation unit includes a first calculation block that adds or subtracts output from the first to fourth magnetoelectric transducers, and outputs a calculation result.

Magnetic field measuring device

A method for producing compounds containing a bis(perfluoroalkylsulfonyl)methyl group or salts thereof, wherein the compounds have high acidity and hydrophobicity and are useful as raw material compounds for a resin.

Method for producing compound containing BIS (perfluoroalkylsulfonyl) methyl group and salt thereof, and solid electrolyte membrane produced using same

Disclosed is a proton conducting polymer membrane formed by laminating a plurality of solid electrolyte membranes. This proton conducting polymer membrane is one prepared by laminating at least one layer of a solid electrolyte membrane formed by using a resin having a bis(perfluoroalkanesulfonyl)methide group in the chemical structure. This solid electrolyte membrane has a superior proton conductivity without transmitting the fuel (methanol or hydrogen).
