Life time test in direct borohydride fuel cell system
The electric performances of direct borohydride fuel cells (DBFCs) are evaluated in terms of power density and life time with respect to the NaBH 4 concentration. A DBFC constituted of an anionic membrane, a 0.6 mg Pt cm −2 anode and a commercial non-platinum based cathode led to performances as hig...
