To find optimized GDL in each of the anode and cathode in HT-PEMFC, 4 kinds of GDL(SGL38BC, SGL36BB, JNT30A3, H23C2) were compared by 3 kinds of analysis method(Mercury Intrusion Porosimetry, image processing and electrochemical analysis). JNT30A3 with the largest crack area and porosity of micro porous layer(MPL) could produce the highest Maximum power (2.758W) compared to other GDLs in cathodes. In the anode, H23C2 with the smallest crack area of MPL and thinnest thickness of GDL could produce the highest performance (0.649V at 0.2A/cm2) compared to other GDLs. |
