Graphitized carbon as a mesoporous layer for unitized regenerative fuel cell applications |
| 초록 |
The development and characterization of mesoporous layer (MPL) for application in unitized regenerative fuel cells (URFCs) are reported in this research work. The carbon corrosion is the major effect to the degradation of MEA and electrochemical performances in a unit cell process. Here, we have associated the Graphitized carbon (Gr-carbon) as a MPL in electrodes instead of Gr-carbon as a supportive material to the electrocatalysts. In FC mode, the performance of ORR has significantly improved to addition of MPL in MEA. The potential value of an anode with Gr-carbon MPL is 0.708 V at 1 A cm-2, it is considerably higher than the non-MPL (0.461 V) and Am-carbon MPL (0.706 V) under identical conditions in FC mode. The round-trip energy efficiency values are 27.24, 41.79 and 43.77 for non-MPL, Am-carbon MPL and Gr-carbon MPL respectively, it revealing that the anode with Gr-carbon MPL has greater efficiency in electrochemical performances for further development to URFC devices. |
