Regarding the gasket or "glue" material, the following resource can be useful:
http://www.darcoid.com/images/Image/Tab/PERLAST/Elastomer%20guide%20chemical%20compatibility.pdf search for lithium chloride (they don't reference palladium chloride nor anything palladium unfortunately). Since there will be H+ and OH- ions too, compatibility with hydrochloric acid and with lithium hydroxide might be useful too? It was in this resource BTW that I had seen the highly inert rubber I mentioned to you once, it's FFKM (Perfluoroelastomer), they say it's "effectively a rubber form of PTFE". Its compatibility is quoted as "1 excellent" with all the above chemicals, I have no idea of the cost though.
