  • Patent number: 11108087
    Abstract: Compounds (salts) for use as electrolytes, e.g. in batteries such as Li ion, Na ion and Mg ion batteries are provided. The negative ions (anions) of the compounds are complex molecules containing superhalogens, and thus exhibit improved safety, and yet have electron affinities that are equal to or greater than those of halogens. In addition, the binding energy between Li+ and the anions is relatively small so ions can move easily from one electrode to the other in solutions in which the compounds are dissolved. A further advantage is that the affinity of the electrolyte for water is also relatively low so that batteries in which the electrolytes are used have longer lives than those of the prior art.

  • Patent number: 11050071
    Abstract: There is provided an inspection method for a fuel cell or a fuel cell stack that ensures performing a leakage inspection minutely in a shorter time compared with the conventional inspection. The inspection method includes an enclosing step, an external leakage inspection step, and a communication leakage inspection step. The enclosing step encloses a first gas passage, a second gas passage, and a refrigerant passage in the fuel cell or the fuel cell stack to form three sections. The three sections are a first section, a second section, and a third section independent of one another. The external leakage inspection step simultaneously supplies an inspection gas to two or more sections among the three sections for pressure boosting to perform an inspection for leakage of the inspection gas from the two or more sections after boosting pressures to an outside.
