Iimpawu ze-coke ye-petroleum ene-calcined ziqulathe i-carbon ephezulu, umxholo ophantsi wokuguquguquka, uxinano oluphezulu kunye nokuqina. I-coke ye-petroleum ene-calcined ingasetyenziswa njengezinto eziluhlaza okanye ezongeziweyo ekuvelisweni kwe-carbon black, nto leyo echaphazela ukusebenza kunye nomgangatho we-carbon black, esetyenziswa kwirabha, i-inki, ii-coating kunye namanye amashishini. Kwintsimi yamandla amatsha afana nee-fuel cells, ingasetyenziswa njengezinto eziluhlaza kwizixhobo ze-electrode, kwaye emva konyango olukhethekileyo kunye nokucutshungulwa, ingasetyenziselwa ukulungiselela ii-electrodes ezine-conductivity yombane elungileyo kunye neempawu ze-catalytic ukuxhasa uphuhliso lwee-fuel cells.
