Munyaya ye electrochemistry, kushanda zvakanaka uye kushanda zvakanaka kwemasero e electrochemical ndiko kwakakosha. Pakati pezvikamu zvakasiyana-siyana zvinobatsira mukushanda zvakanaka, ma anode asingachinji anoita basa rakakosha. Aya ma electrodes asingachinji haasi kungova zvikamu zvisingachinji; ndiwo musimboti we electrochemical system, achipesvedzera reaction kinetics, kugadzikana, uye hupenyu hwesero.
Anode dzisingachinjidzakagadzirirwa kuti dzirambe dziri munzvimbo yadzo panguva yekushanda kwemagetsi, zvichipa nzvimbo yakagadzikana yekuchinja kwe oxidation kunoitika pa anode. Kugadzikana uku kwakakosha kuti pave nekushanda kwakasimba nekufamba kwenguva. Kusiyana ne anode dzinofamba kana dzinotenderera, anode dzisingachinji dzinobvisa kuomarara kunobatanidzwa nekufamba kwemuchina, zvichiita kuti dhizaini nekushanda kwemasero emagetsi zvive nyore.
Chimwe chezvakanakira zvikuru zveanode dzisingachinji ndiko kugona kwavo kuwedzera kushanda zvakanaka kwe electrochemical reactions. Nekupa nzvimbo yakagadzikana yekufambisa maerekitironi, anode dzisingachinji dzinokurudzira oxidation ye reactants, nokudaro zvichiwedzera huwandu hwemagetsi uye kuvandudza mashandiro ese emasero. Izvi zvakakosha zvikuru mumashandisirwo akadai se electrolysis, fuel cells, uye mabhatiri, uko kuwedzera kushanda zvakanaka kwe electrochemical reactions kunogona kukanganisa zvakanyanya kuburitswa kwesimba uye mari yekushanda.
Pamusoro pezvo, ma anode asingachinji anogona kugadzirwa achishandisa zvinhu zvakasiyana-siyana kuti aite kuti ashande zvakanaka. Zvinhu zvakajairika zvinosanganisira graphite, platinum, uye ma oxide esimbi akasiyana-siyana, rimwe nerimwe rine hunhu hwakasiyana hunogona kuwedzera reaction ye electrochemical. Semuenzaniso, ma anode e graphite anozivikanwa nekugona kwawo kufambisa zvinhu zvakanaka uye kugadzikana kwemakemikari, zvichiita kuti ave akakodzera kushandiswa kwakasiyana-siyana. Kune rumwe rutivi, ma anode e platinum anowanzo shandiswa mumasero emafuta anoshanda zvakanyanya nekuda kwehunhu hwawo hwakanaka hwe catalytic.
Kugadzirwa kweanode isingachinji kunoitawo basa rakakosha mukushanda kwayo. Zvinhu zvakaita senzvimbo yepamusoro, maburi, uye morphology zvinogona kukanganisa zvakanyanya mashandiro emagetsi. Nzvimbo yakakura yepamusoro inobvumira nzvimbo dzinoshanda kuti dziite chimwe chinhu, nepo chimiro chine maburi chinogona kuwedzera kutakurwa kwezvinhu, zvichiita kuti reactants isvike kune anode zvinobudirira. Vaongorori vanogara vachitsvaga magadzirirwo matsva nezvinhu kuti vawedzere kuvandudza mashandiro eanode isingachinji uye kusundira miganhu yetekinoroji yemagetsi.
Pamusoro pekuvandudza mashandiro, ma "anode" asingachinji anobatsira kuwedzera hupenyu hwemasero emagetsi uye kuvandudza kugadzikana kwemasero. Nekupa puratifomu inogara iripo uye yakavimbika yezviitiko, anobatsira kuderedza matambudziko akadai sekuora kwema "electrode" uye "passivation", izvo zvinogona kukonzera kuti mashandiro adzikire nekufamba kwenguva. Kugadzikana uku kwakakosha zvikuru mumaindasitiri, uko mari yekushanda uye yekugadzirisa yakakwira.
Sezvo kudiwa kwemhinduro dzesimba dzinoshanda kuri kuramba kuchikura, kukosha kwema anode asingachinji mumasero emagetsi hakugone kurerutswa. Kugona kwavo kuwedzera kushanda zvakanaka kwemaitiro, kuvandudza kugadzikana, uye kuwedzera hupenyu hwemasisitimu emagetsi kunoita kuti ave chikamu chakakosha mukuvandudzwa kwetekinoroji yepamusoro yesimba. Kubva pasimba rinogona kudzorerwa kusvika kumhinduro dzekuchengetedza simba, anode asingachinji ari kugadzira nzira yeramangwana rakagadzikana uye rinoshanda.
Muchidimbu,anode dzisingachinjindiwo musimboti wemasero emagetsi anoshanda zvakanaka. Magadzirirwo awo, kusarudzwa kwezvinhu, uye kugadzikana kwekushanda ndizvo zvinhu zvikuru zvinopesvedzera mashandiro emhando dzakasiyana dzemashandisirwo emagetsi. Sezvo tsvakiridzo nekuvandudzwa kwenzvimbo iyi zvichiramba zvichifambira mberi, tinogona kutarisira kuona mhinduro itsva dzinoshandisa hunhu hwakasiyana hwema anode asingachinji, dzichifambira mberi tekinoroji yemagetsi uye mashandisirwo ayo muhupenyu hwedu hwezuva nezuva.
