Includes anodes , coils , and lined tanks for plating industry , as well as variety of sheeted materials for protection against radiation . These can use sacrificial anodes ( galvanic coupling of a sacrificial material with the structure ) or impressed current ( use of a non-consumable anode with a DC source ) . As a result , zinc as an anode or sacrificial metal coating does not perform the same as in atmospheric conditions . The zinc anodes which are removed from used batteries are recharged in a regeneration process and reformed into new anodes , which are then placed back into the vehicles . Even if some of us get a little extreme about it , those individuals will serve as sacrificial anodes , and help the mainstream shift over a little towards accepting atheism . Our research in this area has focused on the development of anodes and anode catalysts for SOFCs that allow the direct use of hydrocarbons as the fuel without the need for reforming them to produce hydrogen . This work involves building model SOFCs and performing spectroscopic studies of the anodes . The grommet electrically insulates the anode from the cathode . A major problem is that typical anode materials can only operate with hydrogen , so that practical fuels , like methane and diesel fuel , must first be reformed to hydrogen .
