成する。The mixing ratio of both resin powders should be 40 to 60% in total; if it is higher than this, it will become hard and loose and lack elasticity, and if it is lower than this, the bonding force of Sic& will be insufficient and the strength will be poor. I have a problem. Also, the ratio of secondary particles to primary particles is
Even if it's the same, it's definitely an Ffli person! The larger the number, the better. The sealing material of the present invention has the same properties as the conventional fluororesin sheet, with the sealing material on both sides of each waste separation plate (2) /L/ff1i (
31f3) and [4)+4+ However, when assembled into a battery stack (S), a sealing material is placed between the sealing surface (3) of the force separation plate and the adjacent gas separation plate (2). (7
