Abstract
A novel and cost-effective electrode binder consisting of chitosan chemical hydrogel (CCH) is reported for direct borohydride fuel cells (DBFCs). The DBFCs have been assembled with Misch-metal-based AB5 alloy as anode, carbon-supported palladium (Pd/C) as cathode and polyvinyl alcohol (PVA) hydrogel membrane electrolyte (PHME) as well as Nafion®-117 membrane electrolyte (NME) as separators. Operating in passive mode without using peristaltic pump and under ambient conditions of temperature as well as pressure, the DBFC exhibited a maximum peak power density of about 81 mW cm - 2.
