제목 | Observation of electrochemical characteristic of phosphoric acid doped PBI based high temperature PEMFC in the temperature range 120-160 ℃ |
초록 | High-temperature (90–200 ◦C) proton exchange membrane fuel cells (PEMFCs) have been considered the next generation of fuel cell because of their advantages over those operated at lower temperatures (usually below 80 ◦C). These advantages include: (1) faster electrochemical kinetics, (2) improved and simplified water management, (3) effective thermal management and (4) improved contamination tolerance. In this study, We prepared a single cell using a commercially MEA, and autonomously produced a single test station equipped with a reformer, and observed the performance and electrochemical characteristics of the single cell. Furthermore the effect of stoichiometry on the single cell electrochemical properties were investigated by electrochemical impedance spectroscopy(EIS) measurements. We conducted long-term experiments for 500 hours to observe the durability of single cells. |
