摘要

A method for dissolving a hardened glass solder, a method for separating components joined by a glass solder, a method for disassembling a fuel cell, and an apparatus for disassembling a fuel cell, include heating the hardened glass solder in a melt of a hydroxide. As a result, components which had been joined through the use of the hardened glass solder are able to be reused or subjected to a recycling process.
