“…The cell potential represents the sum of the equilibrium potential and overpotential associated with multiple resistances [32] . Both the Gibbs free energy change (thus the equilibrium potential) and the overpotential of the overall water dissociation reaction decrease with the increasing temperatures [32,33] . The reduction of electrochemical resistances is measured by electrochemical impedance spectroscopy (EIS) measurements (Figure 1e).…”

“…[32] Both the Gibbs free energy change (thus the equilibrium potential) and the overpotential of the overall water dissociation reaction decrease with the increasing temperatures. [32,33] The reduction of electrochemical resistances is measured by electrochemical impedance spectroscopy (EIS) measurements (Figure 1e). In the Nyquist plot, the intersection point of the impedance curve with the xaxis (real part of the impedance) identifies the solution resistance (R s ), which decreases from 0.78 Ω at room temperature, to 0.24 Ω at 120 °C (Figure 1e and Table 1).…”

Ammonia is an indispensable commodity and a potential carbon free energy carrier. The use of H permeable electrodes to synthesize ammonia from N 2 , water and electricity, provides a promising alternative to the fossil fuel based Haber-Bosch process. Here, H permeable Ni electrodes are investigated in the operating temperature range 25-120 °C, and varying the rate of electrochemical atomic hydrogen permeation. At 120 °C, a steady reaction is achieved for over 12 h with 10 times higher cumulative NH 3 production and almost 40-fold increase in faradaic efficiency compared to room temperature experiments. NH 3 is formed with a cell potential of 1.4 V, corresponding to a minimum electrical energy investment of 6.6 kWh kg À 1 NH 3 . The stable operation is attributed to a balanced control over the population of N, NH x and H species at the catalyst surface. These findings extend the understanding on the mechanisms involved in the nitrogen reduction reaction and may facilitate the development of an efficient green ammonia synthesis process.

“…[42] Electrolysis is a process that employs electrical energy to separate water into its fundamental components, i. e., hydrogen and oxygen. [43] This process can be powered by renewable energy sources to produce green hydrogen with zero carbon emissions. [44] Photolytic processes involve splitting water with the use of sunlight through a host of biological/ electrochemical methodologies.…”

The research in energy storage and conversion is playing a critical role in energy policy as the innovation and technological progress are essential for achieving the energy transition and climate neutrality goals. Hydrogen Fuel Cell technology is considered a strategic element in the pursuit of sustainable and clean energy solutions. This technology is increasingly gaining attention in recent years as a potential substitute to conventional non‐renewable energy sources. Fuel cell technology can be employed for domestic/commercial use along with powering the transportation sector which currently employs the use of conventional battery systems. However, these systems pose severe limitations with respect to longer charging times and limited distance range. This review article aims at providing a comprehensive methodical overview of hydrogen‐based fuel cell technology along with key concepts, present day scenarios, including overview of the market and industry trends, government policies and initiatives, along with major stakeholders involved in scaling up the technology for mass consumption. The outlook of fuel cells, including their capability to revolutionise the energy sector is discussed. The technological advancements and breakthroughs on the horizon along with the challenges and safety concerns related to the widespread acceptance of fuel cells are analysed.
