Navigating Excellence: A Comprehensive Review on the Versatile Potential of High-Performance N-Heterocyclic Triazole as an Electrolyte for Proton Exchange Membrane Fuel Cells

“…11 Based on the type of electrolytes employed, fuel cells are classified as solid oxide fuel cells, 5 polymer electrolyte fuel cells, 12 alkaline fuel cells, 13 molten carbonate fuel cells, 14 direct methanol fuel cells, 15 microbial fuel cells, 16 and phosphoric acid fuel cells. 17 All these types will follow the same working principle for energy production with different operating temperatures and efficiencies in energy production. High power density, operating conditions at low temperature, and easy scale-up features project this polymer electrolyte fuel cell to be highly efficient, more than the others.…”

Electrochemical-catalytic NH3 synthesis from H2O and N2 using an electrochemical cell with a Ru catalyst, Pd–Ag membrane cathode, and NaOH–KOH molten salt electrolyte at 250 °C

“…20 Phosphate electrolytes have been studied with the expectation of being a practical electrolyte, given the commercialization of phosphoric acid fuel cells (PAFC) operating at around 200°C. 26,27 However, large-scale water electrolysis predominantly utilizes alkaline water electrolysis (AWE) at temperatures below 100°C. 28,29 There is hope for the application of this electrolyte in NH 3 synthesis by raising the temperature range to between 200 and 250°C.…”

Experimental Study of the Characteristic of a PEM Reversible Fuel Cell

“…Recognised, so far, despite the ongoing extensive research, are more than 20 types of fuel cells (Giap et al, 2022), (Mitzel et al, 2021), (Ou et al, 2021), (Sharaf & Orhan, 2014) and the most popular and widespread, in view of their technical parameters, are (Akinyele et al, 2020)polymer electrolyte membrane fuel cell (PEMFC), alkaline fuel cell (Gülzow & Schulze, 2008), phosphoric acid fuel cells (Fuller & Gallagher, 2008), solid oxide fuel cells (Alaswad et al, 2022), molten carbonate fuel cells (Rexed et al, 2015) and direct methanol fuel cells (Joghee et al, 2015).…”
