The metal with a lower potential in the galvaniccell will be anodic and will corrode.
原电池中具备较低电势的金属是阳极的而且会受到腐蚀。

By insulating flange at the junction between the new and old pipe, the long line galvaniccell is "broken up" - the anode (new pipe) is electrically separated from the cathode (old pipe).
在新、旧管子连接处安装绝缘法兰，破坏了长管道的原电池，即：阳极(新管子)和阴极(旧管子)间电断路。

Galvaniccell type hydrogen sensors and fuel cells belong to the former, and hydrogen pump, steam electrolyzer and membrane reactors to the latter.
