Effect of Carbon Black and Carbon Nanotube Concentration in Carbon Paper on the Electrical Properties for Using Gas Diffusion Layer |
| 초록 |
In this work, we studied the gas diffusion layers (GDLs) made from carbon fibers paper for using gas diffusion matrix (GDM) in polymer electrolyte membrane fuel cells (PEMFCs) by wet processing. Carbon blacks (CBs) and carbon nanotubes (CNTs) were added in carbon paper during impregnating phenol resin to investigate the effect of CBs and CNTs on the electrical properties of carbon paper. We used 0.1 g of 6 ㎜ chopped carbon fibers for making carbon paper preform with 5ⅹ5 ㎠ size. Various contents of CBs and CNTs were added and estimated. The dispersion states of carbon fibers were investigated by scanning electron spectroscopy (SEM) and the electric resistivity of carbon paper was measured using two probe techniques. It was confirmed that the conductivity of carbon paper increased with increasing carbon black content. |
