Title:
膜電極接合体の活性化方法及び膜電極接合体とそれを用いた固体高分子型燃料電池
Document Type and Number:
Japanese Patent JP2011520237
Kind Code:
A
Abstract:
In the conventional initial operation and activation processing (pre-processing), a processing time of ten odd hours or more is usually required, and special processing equipment and complex processing steps are needed. An aqueous alcohol solution is prepared, a membrane electrode assembly (10) for a solid polymer-type fuel cell is brought into contact with the aqueous alcohol solution, and the assembly (10) is then washed with water. Then, the membrane electrode assembly (10) is sandwiched between bipolar plates (30, 31) to configure a unit cell. The unit cell is sandwiched between collector plates (50, 51), a plurality of unit cells sandwiched between the collector plates are stacked, and the stack is tightened and held between insulating plates (60, 61) and end plates (70, 71) to produce a solid polymer-type fuel cell.
