| 摘要 |
The present disclosure is directed to a process for treating gas electrodes containing a wetproofing (backing) layer which contains a polytetrafluoroethylene (PTFE) in conjunction with a water-soluble pore-forming agent and a PTFE-containing active layer to preserve and enhance their structural integrity which comprises contacting the electrode first with an alkylene polyol, or other water-soluble organic material having a plurality of hydroxyl groups, at temperatures ranging from about 50 DEG to about 100 DEG C. for a sufficient period of time to thoroughly wet the PTFE-containing active layer thereof, and thereafter contacting the thus-treated electrode with water in one or more washing steps to substantially remove the pore-forming agent. Between the hot soak with the alkylene polyol, or equivalent material, and the water wash(es), the electrode can optionally be dried.
