Abstract
A prepreg for fuel cell obtained by soaking reinforcing glass fiber cloth in resin mixture and having the soaked cloth pre-dried to form incompletely cured prepreg which can be press-cured under temperature range of 60□˜200□ to provide good mechanical and electrical property and high bonding strength, and when applied to fuel cell for bonding together the parts and components of the fuel cell the prepreg can also provide the effect of preventing crossover of fuel of the fuel cell and helping to the normal operation of the fuel cell.
Claims8
A prepreg applied for fuel cell obtained by soaking a reinforcing glass fiber cloth in resin mixture and pre-drying the soaked cloth to form incompletely cured bonding material which shall be press-cured under temperature range of 60˜200□ with an amount of the resin mixture used making up 30˜95% of the total weight of the prepreg and the major components of the resin mixture comprises:
- (a) epoxy resin makes up 20˜99 wt % of the total solid of the resin mixture with an equivalent epoxy weight of 150˜10000 g/eq approximately;
