We report the small molecules utilizing new electron-deficient unit, 2,2-dimethyl-2 H -benzimidazole (MBI) and phenanthro[9,10- c ][1,2,5]thiadiazole (PT), for the photovoltaic application. Donor-acceptor-donor (D-A-D) types of conjugated small molecules containing benzo[1,2- b ;3,4- b ′]dithiophene (BDT) as electron rich unit and MBI and PT as...
Membrane electrode assemblies (MEAs) for a high temperature polymer electrolyte membrane fuel cell (HTPEMFC) were fabricated using acid-doped polybenzimidazole (PBI) as the electrolyte membrane and polytetrafluoroethylene (PTFE) as the electrode binder. PTFE concentrations of 20, 30, and 45 wt% in the electrode were evaluated to determine the optimal binder content. Additionally, the influence of...
