Abstract
Description
ここで、m1はセパレータ4の質量、m2は正極6の質量、Aは吸着搬送時の振動による加速度である。
このセラミックス層23にかかる線圧Pが、セラミックス層23の単位長さ当たりの必要剥離強度Yよりも小さくなるように、幅方向Wに沿った接着剤46aの塗布点数aおよび個々の接着剤46aの塗布径bを設定する。
上記(3)式を解くと、aは7.25となる。従って、幅方向Wに沿って塗布される接着剤46aの塗布点数aは8個に設定される。
Claims (3)
- 少なくとも一方の面に耐熱層を備えたセパレータの両面に、モノセル搬送方向と直交する幅方向に離れた複数の点において接着剤を塗布したシート状の正極および負極をそれぞれ接合するモノセルの製造方法において、
上記幅方向における接着剤の塗布点数と各々の接着剤の塗布径との積を塗布長としたときに、
吸着搬送時に重量および加速度に基づき耐熱層に加わる力を上記塗布長で除した値が、耐熱層の単位長さ当たりの必要剥離強度よりも小さくなるように、上記塗布点数と上記塗布径とを設定した、モノセルの製造方法。 - 上記正極は一対のセパレータの間に配置されている、請求項1に記載のモノセルの製造方法。
- 上記セパレータは上記正極に対向する面に耐熱層を備えている、請求項1又は2に記載のモノセルの製造方法。
