Overview of hydrogen production technologies for fuel cell utilization

Engineering Science and Technology an International Journal, Год журнала: 2023, Номер 43, С. 101452 - 101452

Опубликована: Июнь 1, 2023

With rapidly depleting fossil fuels and growing environmental alarms due to their usage, hydrogen as an energy vector provides a clean sustainable solution. However, the challenge lies in replacing mature fuel technology with efficient economical production. This paper techno-economic, overview of H2 production technologies. Reforming is still considered backbone large-scale Whereas renewable has technically advanced improved, its cost remains area concern. Finding alternative catalytic materials would reduce such costs for Taking mid-term timeframe, viable scenario solar integrated water splitting methods, or from biomass gasification. Gasification preferred option it carbon neutral cost-effective, producing at 1.77 – 2.77 $/kg H2. Among other uses industrial applications, most approach use cells generating electricity. Commercialization cell hindered by lack infrastructure. Fuel units should be achieve desired results. Case studies different technologies are presented end this paper, depicting environmentally acceptable compared fuels.

Hydrogen production via steam reforming of different fuels: thermodynamic comparison

International Journal of Hydrogen Energy, Год журнала: 2023, Номер 55, С. 1143 - 1160

Опубликована: Ноя. 25, 2023

Hydrogen, a sustainable energy source, has potential to address climate change. However, traditional steam reforming processes produce CO2. Alternative fuels like bio-alcohols, biogas, and LPG are being adopted for processes. This study presents thermodynamic comparative examination of employing different fuels, including methane, methanol, ethanol, propane, glycerol, biogas. The analysis focuses on the hydrogen yield, environmental impact, requirements these comparison with experimental results. analyses were conducted using AspenPlus® software, minimizing Gibbs free under specified conditions (T = 25–1000 °C, n 1–10, P 1–40 bar). Among examined, methane exhibited highest yields, reaching maximum values 96.10 %, 95.86 95.26 % respectively at 600 1 bar, water-to-fuel ratio 10. Ethanol, propane achieved yields 89.66 86.55 84.03 700 °C same pressure ratio.

The Operating Parameters, Structural Composition, and Fuel Sustainability Aspects of PEM Fuel Cells: A Mini Review

Fuels, Год журнала: 2022, Номер 3(3), С. 449 - 474

Опубликована: Авг. 3, 2022

This mini review discusses the sustainability aspects of various fuels for proton exchange membrane fuel cells (PEMFCs). PEMFCs operate by converting chemical energy in a into electrical energy. The most crucial parameters operation process are temperature, pressure, relative humidity, and air stoichiometry ratio, as presented this work. classical structure PEMFC consists membrane, anode electrode, cathode catalyst layers (CLs), microporous layer (MPLs), gas diffusion (GDLs), two bipolar plates (BPs), flow channels (GFCs). mechanical behavior conductivity protons highly dependent on MEAs. their production paths from sustainable sources. For to be renewable sustainable, hydrogen electrolyzer could powered solar energy, wind geothermal or hydroelectric produce hydrogen, which turn fed cell. paper also reviews biomass-based routes production.

A review of hydrogen production optimization from the reforming of C1 and C2 alcohols via artificial neural networks

Fuel, Год журнала: 2023, Номер 345, С. 128243 - 128243

Опубликована: Март 28, 2023

Hydrogen production from different fuels has received extensive study interest owing to its environmental sustainability, renewability, and lack of carbon emission. This research aims investigate how artificial neural networks (ANNs) are employed optimize operating parameters for the catalytic thermochemical conversion methanol ethanol their impact on hydrogen production. According ANN model, peak (99%) occurs at lower temperatures 300 °C with a maximum yield 2.905 mol, whereas (85%) 500 dehydrogenation C-C bond-breaking process. A steam-to-carbon (S/C) ratio (3.5) was advantageous steam reforming (MSR), high concentration 10–15 vol% favorable (ESR). Ni (10 wt%), Co wt%) were optimum metal combinations in catalyst reformation temperature 450 °C. The catalysts producing converting those synthesized through co-precipitation. attained sintering 560–570 technique is cost-effective, quick, precise, vast potential produce energy, may give significant benefits industrial applications.
