Ramli Sitanggang

Abstract


ABSTRAK: Salah satu cara untuk mengurangi biaya pembuatan PEM Fuel Cell adalah mengurangi tebal lapisan. Lapisan terletak diantara GDL dengan elektrode PEMFC. Lapisan ini, untuk menyanggah elektrode yang dinyatakan dengan tebal, porositas, diameter pori, luas permukaan aktif. Pada kertas kerja ini, dilakukan pemetaan hasil hasil penelitian lapisan tipis yang sudah dilaporkan dan hasil pengujian untuk mengetahui karakteristik pengurangan  ketebalan lapisan tipis tersebut. Hasil pemetaan dan  analisis  didapatkan  pada ketebalan berkisar 250 µm. Dalam  pengujian ketebalan 250 µm masih dapat dikurangi dengan mesin sepray sekitar 145 µm dengan densitas karbon sekitar  2 mg cm-2., tetapi prestasi PEMFC lebih kecil dari prestasi tebal 250 µm.

 

Kata Kunci: lapisan tipis GDL; pengurangan lapisan; carbon density; ukuran lapisan; prestasi lapisan tipis

ABSTRACT: One way to reduce the cost of making PEM Fuel Cells is to reduce the thickness of the layer. The layer is located between GDL and PEMFC electrode. This layer, to refute the electrode, is expressed with thickness, porosity, pore diameter, active surface area. In this working paper, the results of the thin film research results have been mapped and the results of the tests are to determine the characteristics of the thin layer thickness reduction. The mapping and analysis results were obtained at thicknesses ranging from 250 µm. In testing the thickness of 250 µm can still be reduced by a spray machine of 145 µm with a carbon density of about 2 mg cm-2, but PEMFC's performance is smaller than the achievement of 250 µm thick.

Keywords: GDL thin layer; layer reduction; carbon density; layer size; thin layer performance
