High-temperature polymer electrolyte membrane fuel cell as a sustainable green technology has been developed throughout the years as it provides several benefits compared to Nafion-based fuel cells (e.g., CO tolerance, improved kinetic and enhance water management). Polybenzimidazole which one of the best membrane candidates was extensively studied due to excellent properties to be used in high-temperature application. Impregnating polybenzimidazole with phosphoric acid are most commonly practised as an electrolyte membrane in the PEMFC. In this paper, recent advancement of the existing literature regarding work revolving polybenzimidazole to improve the performance of phosphoric acid doped polybenzimidazole membrane for high-temperature polymer electrolyte membrane fuel cell are reviewed. Notable works such as using aluminium containing silicate (Al-Si), silicon carbide whisker (mSiC) and sulfonated graphene oxide in the composite PBI derivatives were observed. Proton conductivity are recorded at 0.371, 0.271 and 0.280 S/cm, respectively.

Abstract Modern H2-based energy storage and conversion devices require a polymer electrolyte membrane (PEM) fuel cell–based integrated power system with synergistic heat integration. The key issue in integrated power systems is developing a PEM that can operate at 200–300 °C. However, currently used phosphoric-acid-based high-temperature PEM fuel cells limited stability at higher operating temperatures. Herein, we introduce a cerium hydrogen phosphate (CeHP) PEM that conducts protons above 200 °C through a self-assembled network (SAN). The SAN-CeHP-PBI reached maximum power densities of 2.4 W cm-2 and operate stably for over 7000 minute without any voltage decay at 250 ℃ under H2/O2 and anhydrous conditions. The developed fuel cell can be combined with an external hydrogen generator that uses a liquid hydrogen carrier such as N-ethylcarbazole and methanol as fuel, thus achieving a high energy efficiency. The thermal stability and fuel flexibility of these SAN-CeHP-PBI demonstrate potential for commercial applications.
