Halin sinadarai na platinized titanium anodes
An fi son Platinum a saman fili na anode saboda yana da matukar juriya ga lalata kuma yana iya tabbatar da kwararar halin yanzu a yawancin kafofin watsa labarai na electrolyte ba tare da haifar da samuwar rufin rufi a kanta ba. Saboda ba ya lalacewa, ba ya samar da kayan lalata don haka yawan amfani ya ragu sosai.
Platinum ba shi da ƙarfi a cikin gishiri da acid, yayin da yake narkar da shi a cikin ruwa mai ruwa. Babu haɗarin haɓakar hydrogen. (Zaku iya koyo game da ƙurawar hydrogen a cikin labarin Gabatarwa ga Haɗaɗɗen Hydrogen.) Yana ɗaya daga cikin ƙananan karafa da ba kasafai suke yin tsayayya da chlorides na ruwan teku daidai ba.
Titanium yana nuna kyakkyawan juriya ga yanayin ruwa (ruwa musamman). Ba ya mayar da martani tare da mayar da hankali (80%) mafita na karfe chlorides. Duk da haka, yana da saukin kamuwa da hari ta hydrofluoric acid (HF) da kuma zafi hydrochloric acid (HCl) na babban taro. Ko da hydrogen peroxide da zafi nitric acid na iya kai hari ga titanium. Abubuwan da ke haifar da iskar oxygen yawanci ba sa kai hari ga titanium saboda yana samar da murfin oxide mai karewa cikin hanzari. Duk da haka, abubuwan da ba oxidizing irin su sulfuric acid (sama da 5% maida hankali) da phosphoric acid (sama da 30%) na iya kai hari ga titanium. Daga ra'ayi na embrittlement hydrogen, titanium farashin ya fi tantalum a matsayin abu na anode.

Platinum yana da fa'idodin rashin ƙarfi na lantarki, ƙarfin injina, iya aiki da ingantaccen ƙarfin lantarki. Duk da haka, yana da tsada mai tsada. Haɓaka platinum akan titanium da platinum akan tantalum (plated da cladded) kayan ya buɗe yuwuwar yin amfani da waɗannan don kayan anode don kammala ƙarfe da tsarin kariya na cathodic a cikin aikace-aikace masu mahimmanci.
