In this work, we prepared the carbon paper from chopped carbon fibers for using gas diffusion matrix (GDM) in polymer electrolyte membrane fuel cells (PEMFCs) by wet processing. The process of making carbon paper consists of below three steps. ‘Dispersion of chopped carbon fiber’, ‘Preparation of carbon fiber web’, ‘Impregnating of phenol resin’. In whole process, we focused on two steps. First step is dispersion of carbon fiber, five kinds of surfactants were using in the first step to find optimal surfactants for carbon fiber dispersion. The other is the effect of the content of phenol resins 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 phenol resin were impregnated 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.
