Hello everybody, I do electrolysis of NaBr solution with graphite electrodes. Actually the electrical connection is done with stainless steel fastener screw on the graphite electrode plates with copper lug and electrical wire. The stainless steel screw as been pulverize with-in 2 weeks of operation. Is somebody have a better way to connect the electrical wire to the graphite plate ? All the parts arent immerge into the Nabr solution. Thanks Pop
