Fuel cell can use hydrogen from ammonia , Pg13

Key Highlights:

• Scientists enhanced ammonia-powered solid oxide fuel cells by integrating them with a plasma reactor.
• The plasma reactor pre-processes ammonia into hydrogen and nitrogen, boosting power output by 60% at 800ºC.
• The plasma process operates efficiently at room temperature and can recycle waste heat.
• This innovation offers a viable method for utilizing ammonia as a clean and easily storable fuel alternative to hydrogen.

Detailed Insights:

• Solid oxide fuel cells typically suffer from efficiency issues when directly fueled by ammonia due to slow reaction kinetics.
• The integration of a plasma reactor addresses this by efficiently converting ammonia into hydrogen, which then fuels the cell.
• The plasma reactor's ability to function at room temperature and recycle waste heat enhances the overall energy efficiency.
• Using ammonia as a hydrogen carrier circumvents the storage and transportation challenges associated with pure hydrogen.

Scientific/Technical Concepts Involved:

• Solid Oxide Fuel Cell: An electrochemical conversion device that produces electricity by oxidizing a fuel.
• Plasma Reactor: A device that uses plasma to facilitate chemical reactions, such as breaking down molecules.
• Ammonia: A compound of nitrogen and hydrogen (NH3) that can be used as a hydrogen carrier.
