| 제목 | Design of optimal cooling conditions for Polymer Electrolyte Membrane Fuel Cell (PEMFC) using Finite Element Method and various variables affecting it |
| 초록 | As environmental problems arise, hydrogen fuel cells do people spotlight as future energy to replace fossil energy. Polymer Electrolyte Membrane Fuel Cell (PEMFC) is attracting attention as a power source for future automobiles because it has high durability and energy conversion efficiency. It can use methanol or natural gas as fuel in addition to hydrogen. Although it is a PEMFC with high efficiency, it has a narrow operating range with an optimal operating temperature of about 60~80℃. At a temperature higher than this temperature, the decomposition of the separator and catalyst is accelerated, and the stack performance deteriorates. Therefore, it is necessary to safely and efficiently operate the stack through efficient cooling. In this study, the optimal cooling conditions required for PEMFC operation were confirmed according to the amount of air injected and the performance of the heat sink through the Finite Element Method (FEM). In addition, strategies necessary for optimal PEMFC development were explored from the perspective of a material engineering degree. Based on this, it will be possible to develop an optimal PEMFC.
