“…In the literature, several different approaches exist to handle these disadvantages that are a feature of membranes [1][2][3][4][5][6]. For example, one approach is to produce a novel membrane with suitable selective properties; however, this is a complex multistep process [7][8][9]. Another approach consists of modifying a characteristic of a commercial membrane [4][5][6].…”

“…Among all the alcohols, methanol and ethanol [10][11][12][13][14] have been most widely investigated in fuel cell applications due to their well-known reaction mechanisms and relatively high theoretical energy densities (4.6 and 6.1 kWh L -1 ). However, the toxicity of methanol and high volatility of ethanol remain critical issues under practical operation conditions, so glycerol has been considered as a promising alternative fuel for DAFCs because of its relatively low price, convenient storage, non-volatility, non-flammability, and highly-functionalized molecule with a theoretical energy density of 6.4 KWh L -1 .…”

“…Various studies have widely used platinum-based catalyst in low-temperature PEM-DAFCs [12,20]. Although Pt's catalytic activity with respect to alcohols such as methanol [10], ethanol [21], glycerol [22], and ethylene glycol [23] can be very high in DAFCs, the high cost due to scarcity of Pt is problematic.…”

“…As to the passive DMFC, due to the lack of those auxiliary devices, the operational condition such as methanol flow rate or methanol concentration is hard to control, therefore, a passive DMFC shows a lower performance than an active DMFC. In the previous studies, a plenty of researches about optimizing the water management [6,7] and membrane electrode assembly (MEA) design [8][9][10][11][12][13][14][15][16] have been done to reduce the methanol crossover and improve the performance for DMFC.…”

“…Zago et al [11] indicated that the anode MPL is critical to maintain an adequate methanol concentration in anode due to the descent of methanol crossover and the increase of the mass transport loss. Besides MPL, alkaline anion exchange membrane (AAEM) is considered as a desired membrane, comparing by conventional proton exchange membrane (PEM), which is beneficial for reducing the methanol crossover and optimizing the water management [13][14][15][16]. Moreover, the electrochemical kinetics is faster in alkaline media than in acid media [17].…”
