“…(8). The theoretical potential (E) of this reaction is 1.23 V, but at the operational condition the potential is around 0.7 V. This potential result at the maximum output power density is about 1 W cm 2 [30,31] Figure 4 shows a representative schema of the PEMFC operation. The fuel is fed at the anode site and the oxygen is fed at the cathode side.…”

“…Moreover, the open-circuit voltage (OCV) of 3DGO-NS and 3DGO-BS is � 900 mV or higher, ensuring that our prepared membranes exhibit good fuelpenetration resistance. [48][49][50] Furthermore, the functioning of a fuel cell is strongly influenced by the thickness of the membrane, with enhanced performance being associated with thinner membranes. However, thinner membranes also result in higher fuel cross over.…”

The development of efficient proton conductors that are capable of high power density, sufficient mechanical strength, and reduced gas permeability is challenging. Herein, we report the development of a series of aromatic sulfonic acid/graphene oxide hybrid membranes incorporating benzene sulfonic acid (BS), naphthalene sulfonic acid (NS), naphthalene disulfonic acid (DS) or pyrene sulfonic acid (PS) using a facile freeze dried method. For out-of-plane proton conductivity, the 3DGO-BS and 3DGO-NS yielded proton conductivities of 4.4 × 10 À 2 S cm À 1 and 3.1 × 10 À 2 S cm À 1 , respectively; this represents a two-times higher value than that which occurs for three dimensional graphene oxide (3DGO). Additionally, the respective prepared films as membranes in a proton exchange membrane fuel cell (PEMFC) show maximum power density of 98.76 mW cm À 2 for 3DGO-NS while it is 92.75 mW cm À 2 for 3DGO-BS which are close to double that obtained for 3DGO (50 mW cm À 2 ).[a] M.

“…The maximum power density obtained using 3DGO-CNTOX1 is the highest literature value so far reported for a GO-based PEMFC and even higher than that obtained for a Nafion based PEMFC under identical experimental conditions (see Table S2). [31,45,46,49,50]…”

Herein, we report an efficient proton exchange membrane formed from a synergistic combination of graphene oxide (GO) and oxidized single-walled carbon nanotube (CNTOX) by the freeze-drying route that gives rise to enhanced fuel cell power density. At 25 °C and 100% relative humidity (RH), the 3DGO-CNTOX hybrid shows remarkably high out-of-plane and in-plane proton conductivities of 6.64 × 10 À 2 and 5.08 S cm À 1 , respectively. Additionally, the measured performance using prepared films as proton conduction membranes in a proton exchange membrane fuel cell (PEMFC) exhibited a peak power density of 117.21 mW cm À 2 . The high performance of these films can be ascribed to the freeze-dried-driven structural morphology of 3DGO-CNTOX that facilitates higher water retention capacity as well as the synergistic strengthening effect between GO and CNTOX with a highly interconnected proton conduction network. The current results imply that the new 3DGO-CNTOX hybrid material has potential for wide application as a proton exchange membrane.[a] M.
