Results and discussion By increasing the GO loading, the methanol crossover of 1.0 wt% (70 mA/cm2) was lower than the 0.5 wt% (71.2 mA/cm2) which makes the increment of the power density of 1.0 wt% accounts for the methanol crossover in the fuel cell. In another words, less mixed potential at the cathode when using 1.0 wt% of GO than 0.5 wt% in the modified binding layer MEA. At higher GO loading (2 wt% and 5 wt%), the power density starts to drop. This may attributed to the ohmic loss of the fuel cell. On the other hand, the high wt% of GO flakes was able to reduce the methanol crossover to its minimum value. This indicates that the maximum power density of fuel cell can be obtained by optimizing the methanol crossover and proton conductivity at the same time [148]. Slade et al [178], reported that the increase in wt% of the inorganic filler can drop the fuel cell power density due to the poor distribution of inorganic filler. In addition, Prapainainar [167] et al reported that modifying the inorganic filler surface can enhance the surface adhesion interface between the inorganic filler and the polymer which can reduce the methanol crossover in the fuel. In other words, a poor interface between the inorganic and the polymer can increase the chance of pinholes which favour the fuel crossover in the cell. This can happen when increasing the inorganic filler in the polymer matrix due to the poor distribution of the filler in the polymer. However, the following section will show methanol crossover of graphene oxide binding layer in DMFC at different weight percentage per loading. 6.5.1 Effect of Methanol Crossover on GO Modified Binding Layer MEA in DMFC The following tests were conducted by using linear sweep voltammetry to evaluate the methanol crossover of the standard MEA and GO MEAs at different GO wt% loading. To investigate the power density behaviour of different GO wt%, it was found useful to plot the power density and the methanol crossover of GO MEAs side by side in on plot. The following figure shows the methanol crossover and power density of standard and GO MEAs at 70°C and 1.0 M methanol feed concentration in DMFC.
