Abstract
Fuel cell merupakan alat konversi energi ramah lingkungan yang tidak menimbulkan polusi. Fuell cell yang biasa digunakan yaitu, Proton Exchange Membrane Fuel Cell (PEMFC) yang mana merupakan perangkat yang menjanjikan. Namun, untuk menggantikan bahan bakar konvensional membutuhkan peningkatan durabilitas dan pengurangan biaya yang tinggi. Oleh karena itu berkembang ide dengan penggunaan doping nitrogen dan penambahan alloy pada platinum. Karena doping nitrogen dapat meningkatkan konduktivitas dan penambahan alloy dapat menambahkan stabilitas dan aktivitas katalitik yang lebih baik. Pada penelitian ini material yang digunakan adalah Activated Carbon dengan doping nitrogen sebagai carbon support dan Pt-Cr-Co sebagai katalis dengan tujuan untuk menganalisis pengaruh pernambahan komposisi activated carbon yang didoping nitrogen dalam proses sintesis terhadap morfologi,dan performa dari katalis AC/PANI/Pt-Cr-Co/PANI. Terdapat empat variasi perbandingan antara komposisi AC dan PANI yang digunakan yaitu 1:0, 0,66:0,34, 0,5:0,5, 0,34:0,66 yang diberi nama AC, NAC1, NAC2, dan NAC3. Kemudian keempat carbon support yang sudah diaktivasi dilakukan proses sintesis katalis. Pengujian dilakukan menggunakan XRD, SEM, BET, FTIR, CV, dan LSV. Hasil analisa menunjukkan dengan adanya penambahan doping nitrogen, dapat menurunkan intensity karbon dari hasil XRD karbon dan dapat meningkatkan surface area dari hasil uji BET. Untuk hasil cyvlyc voltammetry dari keempat katalis tidak dapat dihitung. Hasil LSV dari elektrokatalis NAC3/Pt-Cr-Co memperoleh initial potential yang paling tinggi pada J 1 mA/cm2 sebesar 0.997 V dibandingkan dengan keempat sampel lainnya. Kemudian untuk AC/Pt-Cr-Co/N memperoleh nilai current density tertinggi dengan nilai 22.1561 mA cm-2

Fuel cell is an environmentally friendly energy conversion tool that does not cause pollution. The fuel cell that is commonly used is the Proton Exchange Membrane Fuel Cell (PEMFC) which is a promising device. However, replacing conventional fuels requires increased durability and high cost reductions. Therefore, the idea developed with the use of nitrogen doping and the addition of alloys to platinum. Because nitrogen doping can increase the conductivity and the addition of alloys can add better stability and catalytic activity. The material used was Activated Carbon with nitrogen doping as carbon support and Pt-Cr-Co as a catalyst with the aim of analyzing the effect of increasing the composition of nitrogen-doped activated carbon in the synthesis process on the morphology and performance of the AC/PANI/Pt catalyst. -Cr-Co/PANI. There are four variations of the ratio between the composition of AC and PANI used, they are 1:0, 0.66: 0.34, 0.5: 0.5, 0.34: 0.66 which are named AC, NAC1, AC2, and NAC3. Then the four activated carbon supports were carried out by the catalyst synthesis process. Tests were carried out using XRD, SEM, BET, FTIR, CV, and LSV. The results of the analysis show that with the addition of nitrogen doping, it can reduce the carbon intensity of the carbon XRD results and can increase the surface area ofthe BET test results. For cyvlyc voltammetry results of the four catalysts cannot be calculated. The LSV results from the NAC3/Pt-Cr-Co electrocatalyst obtained the highest initial potential at J 1 mA/cm2 of 0.997 V compared to the other four samples. Then for AC/Pt-Cr-Co/N obtained the highest current density value with a value of 22.1561 mA cm-2
