line will act •• a suitable plasticizer. When the luoline is drained from the fuel cell. the plas-
ticizing effect of the lesoline is lost and the inner lifter of the ful cell belins to dry out and
subsequent crackinl will occur. This craekinl may penetrate throuah the walls of the cell after
the cell has been refueled. To prevent this failure from Iffectinl serviceable fuel cells which
