Abstract

Kimyasal Buhar
Biriktirme (CVD) yöntemiyle üretilen grafen yapıların bor (B), kobalt (Co)-azot (N)- katkı maddeleri ile Proton Elektrolit Membran (PEM) yakıt
pillerinde elektrokatalizör veya destek malzemesi olarak kullanılabilirliği
incelenmiştir. Bor doplamada amonyum boran (H₃N-BH₃)
doğrudan kullanılırken sodyum borhidrür (NaBH₄) dolaylı olarak
kullanılmıştır. Üretilen örnekler elektrokimyasal yöntemler yanında Taramalı
Elektron Mikroskobu (SEM), Geçirimli Elektron Mikroskobu (TEM), X-ışını
Fotoelektron Spektroskopisi (XPS), Raman ve XRD yöntemleri ile de
tanımlanmıştır. Grafen örneklerin elektrokimyasal oksijen indirgeme reaksiyon
(ORR) ölçümleri döner disk elektrot (RDE) yönetimiyle, geliştirilen
elektrotların yakıt pili testleri 5 cm² aktif alanda yakıt pili test
sistemi ile yapılmıştır. Bor içerikli indirgeme yaklaşımı, yakıt pili
testlerinde PtCo/B/grafen katalizör ile 3000 mA/cm² seviyelerinde
diğer yaklaşımların 3 katı ve üzeri akım yoğunluğu vermiştir.

Production of boron-dopped CVD graphene and fuel cell performance

Abstract

Graphene, produced by chemical vapor deposition (CVD) and modified with
boron (B), cobalt (Co) and nitrogen (N), was investigated as electrocatalyst
and support material for proton exchange membrane (PEM) fuel cells. Ammonia borane
(H₃N-BH₃) was used directly as doping agent while sodium
borohydride (NaBH₄) was used indirectly.  Samples were characterized, in addition to electrochemical
methods, by scanning electron microscopy (SEM), X-ray photo-electron microscopy
(XPS), Raman spectroscopy and XRD. While rotating disc electrodes (RDE) were
used to characterize oxygen reduction reaction capacity of graphene electrodes,
fuel cell testing was carried out with 5-cm² active area single
cell. Boron based reduction of catalysts, compare to other approaches, have
resulted 3 times higher current density reaching 3000 mA/cm² with PtCo/B/graphene
catalyst in fuel cell testing.
