Abstract

Teknologi Fuel cell saat ini yang telah dikembangkan merupakan suatu solusi untuk mengatasi krisis energy pada saat mendatang. Proton-Exchange Membrane Fuel Cell (PEMFC). Merupakan sel elektrokimia yang berbahan bakar hydrogen dan oksigen.. PEMFC merupakan fuel cell banyak digunakan dalam berbagai aplikasi seperti pada bidang otomotif. Namun saat ini penelitian terkait PEMFC ini masih mengalami beberapa kendala mulai dari Konduktivitas carbon support yang kurang baik, stabilitas katalis yang masih kurang efektif, carbon loss yang cukup signifikan dan harga material yang cukup mahal terutama Platinum (Pt). Pada Penelitian ini terdapat beberapa variasi yang dapat mengatasi permasalahan – permasalahan diatas. Yaitu dengan penambahan doping nitrogen dan penggunaan katalis bimetal atau Pt-Cr Alloy yang berfungsi mereduksi harga material yang mahal dan memperlambat degradasi pada Pt saat pengujian durability. Proses sintesis menggunakan metode colloidal dengan elektrokatalis CNT/Pt,CNT/Pt-Cr Alloy, CNT/NC/Pt-Cr Alloy, dan CNT/NC/Pt-Cr Alloy/NC. Selanjutnya akan diperoleh hasil dan dianalisis menggunakan beberapa pengujian XRD,TGA,FTIR,SEM,CV,dan LSV. Hasil penelitian yang didapatkan elektrokatalis dengan penambahan doping nitrogen, Pengaruh doping Nitrogen pada analisis karakteristik menyebabkan kristalinitas dari Carbon dan paduan metal menurun. Hasil morfologi yang dihasilkan elektrokatalis CNT/NC/Pt-Cr/NC menyebabkan pertambahan diamater dari CNT. meningkatkan onset potential yang membuat semakin kekanan, pada hasil elektrokatalis CNT/NC/Pt-Cr/NC onset potential yang didapatkan sebesar 0.83 V dan Current density final yang dihasilkan sebesar 17.94 mAcm-2

The current fuel cell technology that has been developed is a solution to overcome the energy crisis in the future. Proton-Exchange Membrane Fuel Cell (PEMFC). It is an electrochemical cell that is fueled by hydrogen and oxygen. PEMFC is a fuel cell that is widely used in various applications such as in the automotive field. However, currently research related to PEMFC is still experiencing several obstacles, starting from the poor conductivity of carbon support, ineffective catalyst stability, significant carbon loss and quite expensive material prices, especially Platinum (Pt). In this study, there are several variations that can overcome the problems above. Namely with the addition of nitrogen doping and the use of a bimetallic catalyst or Pt-Cr Alloy which serves to reduce the price of expensive materials and slow down the degradation of Pt during durability testing. The synthesis process used colloidal method with CNT/Pt, CNT/Pt-Cr Alloy, CNT/NC/Pt-Cr Alloy, and CNT/NC/Pt-Cr Alloy/NC electrocatalysts. Furthermore, the results will be obtained and analyzed using several XRD, TGA, FTIR, SEM, CV, and LSV tests. The results of the study obtained that the electrocatalyst with the addition of nitrogen doping, the effect of nitrogen doping on characteristic analysis caused the crystallinity of carbon and metal alloys to decrease. The morphological results produced by the CNT/NC/Pt-Cr/NC electrocatalyst caused an increase in the diameter of the CNT. increasing the onset potential which makes it more to the right, in the results of the electrocatalyst CNT/NC/Pt-Cr/NC the onset potential is 0.83 V and the final current density is 17.94 mAcm-2
