Abstract
A bipolar plate for polymer electrolyte membrane fuel cells (PEMFC) was prepared from epoxy/graphite compounds with various carbon nanotube (CNT) using press molding process. In order to decide the cure condition of temperature and time, differential scanning calorimetry (DSC) analysis was carried out and the data was introduced to Kissinger expression and isoconversional expression to get kinetic parameters such as activation energy and pre-exponential factor. Activation energy from Kissinger expression was 82.22 kJ/mol and that from isoconversional expression was 84~88 kJ/mol.
