dc.description.abstract | The porous transport layer (PTL) is essential to effectively remove oxygen and hydrogen gas from the electrode surface at high current density operation conditions. In this study, the effect of PTL with different characteristics such as pore size, pore gradient, interfacial coating was investigated by multi-layered sintered mesh. A water electrolysis single cell of active area of the 34.56 cm2 was constructed, and IV performance and impedance analysis were conducted in the range of 0 to 2.0 A/cm2. It was confirmed that the multi-layered sintered mesh PTL, which have an average pore size of 25 to 57 µm and a larger pore gradient, removed bubbles effectively and thus seemed to improve IV performance. Also, it was confirmed that the catalytic metals such as Ni, NiMo coating on the PTL reduced activation overpotential, but increased mass transport overpotential. | - |
