“…Sorcar et al. prepared the electrolyte supported single cells with YSZ electrolyte, a 5 %Cu/LaTiO 2 N (lanthanum titanium oxynitride) cermet with GDC (Ce 0.9 Gd 0.1 O 1.95 ) anode infiltrated with an alloy of NiFe nanoparticles, and LSCF+GDC/LSCF cathode and investigated their performance in direct ammonia SOFC [133] . A maximum power density of 228 mW ⋅ cm −2 was obtained at 750 °C.…”

The adoption of green hydrogen economy is an indispensable necessity in the current global scenario of environment and energy security. In this endeavor, ammonia is poised to play a key vector of hydrogen to mitigate the challenges arising from transportation, storage and safety. Besides containing a high volumetric and gravimetric hydrogen density, NH3 decomposition into H2 for onsite utilization as a distributed energy source is devoid of greenhouse gases production. In this endeavor, significant technological advancements have been made for in situ production of H2 from NH3 decomposition and the use of NH3 in fuel cell devices to produce electricity. The ammonia decomposition methods to produce H2 mainly involve thermocatalytic, oxidative, electrocatalytic and photocatalytic, among which the catalyst assisted thermal cracking of NH3 has been widely investigated. The research progress in electrolysis of NH3 has been notable in the last couple of years and provides a low‐cost alternative to produce H2 at room temperature. In the area of device development, solid oxide fuel cells (SOFC) have witnessed rapid development in the performances and stability, as ammonia is completely decomposed into H2 and N2 at high operating temperature above ~700 °C.

“…The specific energy of a tank filled with liquid ammonia is about two times higher than a tank filled with hydrogen at 700 bar. 7,8 Ammonia has had a profound global impact since the discovery of its synthesis from hydrogen and nitrogen by Haber and Bosch, now called the Haber-Bosch (H-B) process, which requires high temperature and pressure. With the established infrastructure, over the last decade, momentum has been shifted from the H-B ammonia industry using natural gas (NG) towards using renewable sources, as demonstrated by the opening of a pilot plant by Siemens in Oxfordshire, UK, in 2018 and Nel Hydrogen and Yara in Western Australia.…”
