摘要:
A glass preform manufacturing method includes: generating glass fine particles by hydrolyzing a source gas in an oxyhydrogen flame; depositing the generated glass fine particles to form a torous glass preform; immersing the porous glass preform in an additive solution including an additive solvent in which a compound containing a desired additive is dissolved to impregnate the additive solution into the porous glass preform; first replacing of replacing the additive solvent remaining in the porous glass preform with the replacement solvent by immersing the porous glass preform in which the additive solution remains in a replacement solvent in which a solubility of the additive is lower than that in the additive solvent and having miscibility with the additive solvent; drying the porous glass preform after the first replacing; and sintering the dried porous glass preform to transparently vitrify the dried porous glass preform.

A coupler for a fuel cell according to the embodiment has a socket and a nozzle. The socket is provided on the fuel cell and has a valve body and an urging component for urging the valve body in the direction of closing it. The nozzle is provided on a fuel cartridge for storing a liquid fuel for the fuel cell and has a valve body and an urging component for urging the valve body in the direction of closing it. The valve bodies are opened to supply the liquid fuel in the fuel cartridge to the fuel cell when the nozzle is connected to the socket. The coupler for a fuel cell has a lubricity providing portion for applying lubricating properties. The lubricity providing portion is disposed on the sliding contact surfaces of the socket and the nozzle and makes sliding contact with each other when the socket and the nozzle are connected to each other or separated from each other.
