Patent number: 8592095Abstract: A high molecular nanocomposite membrane for a Direct Methanol Fuel Cell (DMFC), and a Membrane-Electrode Assembly (MEA) and a methanol fuel cell including the same membrane. The high molecular nanocomposite membrane for a DMFC includes a perflurorosulfonic acid polymer (Nation®), high molecular membrane in which hydrophobic silica nanoparticles made from a silane compound having a water repellent functional group are dispersed. Since the high molecular nanocomposite membrane for a DMFC has lower permeability of methanol than a commercially available Nation® high molecular membrane, the MEA fabricated using the high molecular nanocomposite membrane has little crossover of reaction fuel at the negative electrode. In addition, the methanol fuel electrode fabricated using the MEA that includes the high molecular nanocomposite membrane can decrease fuel loss and voltage loss.Type: GrantFiled: January 28, 2011Date of Patent: November 26, 2013Assignee: Kumoh National Institute of Technology Industry-Academic Cooperation FoundationInventors: Yong-il Park, Eun Hyung Kim, Sung Bum Park
