The unique chemical and physical properties of graphene and its derivatives (graphene oxide, heteroatom‐doped graphene, and functionalized graphene) have stimulated tremendous efforts and made significant progress in fuel cell applications. This review focuses on the latest advances in the use of graphene‐based materials in electrodes, electrolytes, and bipolar plates for fuel cells. The understanding of structure‐activity relationships of metal‐free heteroatom‐doped graphene and graphene‐supported catalysts was highlighted. The performances and advantages of graphene‐based materials in membranes and bipolar plates were summarized. We also outlined the challenges and perspectives in using graphene‐based materials for fuel cell applications.

“…In FCs, graphene and its forms have taken up different roles such as catalyst electrode, [203] membrane material, [204] support material [205] and bipolar plates. [206] The efficiency of an FC significantly depends on the electrode reactions. One of which is oxygen reduction reaction (ORR) that occurs at the cathode side.…”

“…The traditional Pt based catalysts have shown incredible electrocatalysis activity for ORR. [206] However, due to its high cost, low availability and other FC issues such as CO poisoning and fuel cross over, scientists suggest the exploitation of the large surface area offered by graphene and its derivatives. [208,209] Park et al suggested that dopants such as S and N, tend to improve the current density and durability of graphene nanosheets for an ORR.…”

Graphene, a two-dimensional (2D) layered material has attracted much attention from the scientific community due to its exceptional electrical, thermal, mechanical, biological and optical properties. Hence, numerous applications utilizing graphene-based materials could be conceived in next-generation electronics, chemical and biological sensing, energy conversion and storage, and beyond. The interaction between graphene surfaces with other materials plays a vital role in influencing its properties than other bulk materials. In this review, we outline the recent progress in the production of graphene and related 2D materials, and their uses in energy conversion (solar cells, fuel cells), energy storage (batteries, supercapacitors) and biomedical applications.

Ammonia can be directly used as fuel to generate electric energy in a low-temperature direct ammonia fuel cell (DAFC), making the DAFC an attractive option for zero-emission transportation. However, with a high-performance and durable DAFC still to be demonstrated, and with the remaining need to identify a suitable first market, the introduction of this technology has been delayed so far. Here, we report a high-performance DAFC stack enabled by a hydrophobic spinel cathode, which achieves the best combination of performance and durability reported to date. Peak power density of 410 mW cm-2 and continuous operation for 80 hours at 300 mA cm-2 were achieved for the first time in 5 cm2 DAFCs, and then successfully scaled up to 50 cm2. Five such cells were assembled into a 75 W DAFC stack using graphite bipolar plates, demonstrating stack performance at the level expected from the single cell tests. The best combination of performance and durability for the single cell and, particularly, the demonstration of the world’s first DAFC bipolar stack, constitute significant milestones in the development of DAFC technology. We also performed an in-depth techno-economic analysis of a 2 kW, 10 kWh DAFC system serving as power source for drones. Based on the DAFC performance demonstrated by us to date, such system can be a competitive power source over hydrogen fuel cells and Li-ion batteries.
