Description
セパレータは好適にはシリコン基板またはガラス基板を含む。半導体製造用のシリコン基板やガラス基板は表面粗度が非常に低いため、その上に成膜プロセスにより形成される拡散層の触媒電極層に向いた側の表面粗度も容易に小さくできる。これにより、拡散層と触媒電極層との間の接触抵抗を低減するとともに、接触抵抗を締め付け圧力によらず概ね一定とすることができる。
まず図6a〜図7aを参照して説明したのと同様のステップによりシリコン基板150の両面に窒化シリコン膜151、152を形成し上面側に金層154とチタン層155を含む導電膜(第1導電膜)153を形成した後、第1導電膜153及び窒化シリコン膜151をエッチング等によりパターニングして、図11aに示すように複数の開口156、157をそれぞれ形成する。
