Abstract
Thermal measurement on the electrode by use of thermistors was carried out in some electrochemical reaction processes. The thermal response reflecting the entropy change for deintercalation of various ions (L+, K+, ClO4-, BF4-), doping of SO42- and H+ elimination, and doping/dedoping of ClO4- was cleary obtained on the graphite, polyaniline and polypyrrole electrodes, respectively. The combination of electrochemical and thermal methods can provide useful information for understanding of reaction process.
