Abstract

Peningkatan konsumsi listrik di Indonesia tidak diimbangi dengan sumber penyedia listrik yang memadai. Indonesia saat ini bergantung pada pembangkit listrik tenaga batubara dimana pasokan yang dimiliki terus menipis. Direct Carbon Fuel Cell (DCFC) merupakan sebuah pembangkit listrik alternatif berbahan karbon yang bekerja dengan mengkonversi biomassa menjadi energi listrik. Penelitian ini bertujuan untuk menganalisis karakterisasi dan nilai power density material karbon menggunakan metode aktivasi karbon dan catalyst gasification dengan variasi 5%, 8%, 10% katalis K2CO3. Pengujian karakterisasi dilakukan dengan menggunakan XRD, TGA, SEM-EDX, dan BET serta pengujian elektrokimia menggunakan OCV, current density, dan power density. Struktur marfologi pada karbon aktif-loaded 5% K2CO3 menunjukkan adanya distribusi K2O secara merata pada permukaan dengan kandungan sebesar 4.53%.Penambahan katalis K2CO3 berdampak pada struktur yang lebih amorf dan membentuk K2O dalam struktur karbon aktif. embentukan K2O meningkatkan reaktivitas gasifikasi (gassification reactivity sebesar 42x10-5) dimana konversi karbon tercapai 70.5% pada temperatur 250 oC dengan penambahan optimal 5%. Surface area mengalami penurunan dengan penambahan K2CO3 yang didapati sebesar 875 m2/g yang diakibatkan oleh adanya pelapisan yang terjadi pada permukaan struktur karbon. Nilai maksimal power density yang didapati jauh lebih tinggi (64.93 mW/cm2) dengan penggunaan katalis 8% K2CO3 dibandingkan tanpa penggunaan katalis (13.26 mW/m2) yang diakibatkan oleh mekanisme catalytic gasification yang terjadi.

The increase in electricity consumption in Indonesia was not matched by an adequate supply of electricity. Indonesia currently relies on coal-fired power plants where supplies were running low. Direct Carbon Fuel Cell (DCFC) as an alternative power plant made from carbon that works by converting biomass into electrical energy. This study aims to analyze the characterization and power density value of carbon material using carbon activation method and catalyst gasification with variations of 5%, 8%, 10% K2CO3 catalyst. Characterization testing was carried out using XRD, TGA, SEM-EDX, and BET and electrochemical testing using OCV, current density, and power density. The morphological structure of activated carbon-loaded 5% K2CO3 showed distribution of K2O on the surface with a content of 4.53%. The addition of K2CO3catalyst has an impact on a more amorphous structure and forms K2O in the structure of activated carbon. The formation of K2O increases the gasification reactivity (gassificaton reactivity of 42x10-5) where the carbon conversion reached 70.5% at a temperature of 250oC with an optimal addition of 5%. The surface area decreased with the addition of K2CO3 which was found to be 875 m2/g caused by the coating that occurred on the surface of the carbon structure. The maximum power density was found higher (64.93 mW/cm2) with the use of 8% K2CO3 as a catalyst than without the use of a catalyst (13.26 mW/cm2) due to the catalytic gasification mechanism
