a massive anode is assembled from many , closely packed modular anodes . although close - packed , the modular anodes are nevertheless spaced apart one from the other . the massive anode has at least substantial inflexibility . it can be particularly useful where a flexible cathode may move toward , and even contact , the anode , e . g ., in electrogalvanizing where a moving sheet from a metal coil being coated may thump against the anode . the individual modular anodes provide a collective , generally planar front face toward the cathode . individual , adjacent modular anodes can be separated at least in part by dielectric spacing members which have portions extending toward the cathode , thereby initially receiving any impact from the cathode .
