Abstract
Sel bahan bakar (fuel cell) adalah peralatan elektrokimia yang
mengubah energi kimia di dalam bahan bakar menjadi energi
listrik secara langsung. Salah satu bahan bakar yang digunakan
adalah metanol (direct methanol fuel cell, DMFC). Tujuan
penelitian ini untuk mengetahui pengaruh massa Zn pada sintesis
graphene sebagai material elektrokatalis PdAu/graphene terhadap
unjuk kerja DMFC. Dari hasil pengujian diperoleh reduktor Zn
sebesar 1.6 gram yang memberikan performa terbaik. Hal ini
didasarkan pada kristalinitas yang baik berdasarkan pengujian
XRD dan bentuk morfologi berupa lembaran graphene yang
sangat tipis berdasarkan pengujian SEM. Dari hasil pengujian CV
yang dilakukan dengan larutan elektrolit KOH 1M menghasilkan
kapasitansi spesifik sebesar 0.58 F/g dan ESA sebesar 3.49
cm2/mg. Sementara kemampuan dalam mengoksidasi metanol
ditunjukkan oleh pengujian CV dengan larutan elektrolit CH3OHKOH
1M yang menghasilkan densitas arus sebesar 0.08 A/g,
onset potential sebesar -0.58 v vs. Ag/AgCl, dan cycleability yang
konstan.

Fuel cell is electrochemical equipment that convert
chemical energy in a fuel into electrical energy directly. One of
the fuel used is methanol (direct methanol fuel cell, DMFC). The
purpose of this research is to determine the influence of mass of
Zn in the synthesis of graphene as a PdAu/graphene
electrocatalyst on the performance of DMFC. According to the
experimental results, 1.6 gram of reductor Zn addition gives the
best performance. XRD test shows good crystallinity and thin
layer graphene morphology can clearly be seen by SEM test. CV
test using 1M KOH electrolyte solution produces specific
capacitance of 0.58 F / g and ESA of 3.49 cm2 / mg. Also, the
ability to oxidize methanol which demonstrated by CV testing in
KOH-CH3OH 1M electrolyte solution produces current density of
0.08 A / g, onset potential of -0.58 V vs. Ag / AgCl, and constant
cycleability.
