Performance Characteristics of Porous Plate Single Cell For PAFC

다공성 바이폴라 사용 단위전지 성능 특성

For the improvement of the performance and life time of phosphoric acid fuel cell, the management of electrolyte in the electrocatalyst layer and electrolyte matrix in the cell structure is very important. Porous bipolar pinto structure, that is known as an advanced type, is generally used for the storage of electrolyte in the cell. In this paper, the single cell was made of the electrode by coating directly electrocatalyst layer on porous bipolar plate. The single cell showed $186\;mA/cm^2$ at 0.6V. This performance is similar to the performance of the conventional nonporous plate single cell. The technology of porous plate single cell could be directly used to the fabrication of stack in order to improve the performance and life time of phosphoric acid fuel cell.
