Passively operated vapor-fed direct methanol fuel cells for portable applications (2008)
Eccarius, S., Krause, F., Beard, K., Agert, C.
The impact of structural parameters and operating conditions has not been researched yet for vapor-fed operation of a DMFC at near-ambient conditions. Thus, a detailed parameter study that included...
Eccarius, S., Tian, X.H., Krause, F., Agert, C.
A vapor-fed DMFC with completely passive operation on both anode and cathode sides was demonstrated and employed for the research of structural parameters and operation under ambient conditions. By...
