Fuel cell technology, a step towards a cleaner tomorrow.
A fuel cell is an electrochemical device that converts the chemical energy of a fuel directly and very efficiently into electricity and heat, eliminating combustion.
The United Nations recently agreed on key issues that the world needs to address by 2030. Progress towards the 17 Sustainable Development Goals will help lift people out of poverty, achieve equality among groups and create a sustainable future.
The big problem we face now is climate change. If we continue to follow current trends in production and consumption, we will continue to emit harmful greenhouse gases, continue to heat the planet, and cause extreme weather events such as the melting of the polar caps. is a good option.
A fuel cell is an electrochemical device that converts the chemical energy of a fuel directly and very efficiently into electricity and heat, eliminating combustion.
The most suitable fuel for such cells is hydrogen, or a mixture of a compound containing a hydrogen fuel cell and an electrolyte, sandwiched between two electrodes. Oxygen passes through one electrode and hydrogen passes through the other and reacts electrochemically to produce electricity, water, and heat.
Automobile transportation fuel cell
In contrast to vehicles powered by internal combustion engines, vehicles powered by fuel cells have very high energy conversion efficiencies, emit almost zero CO2, and emit only water vapor. Fuel cell-powered electric vehicles have advantages over battery-powered electric vehicles in terms of increased efficiency and faster refueling.
Diesel buses are the main mode of public transport in India and emit significant amounts of SPM and CO2. Fuel cell buses and electric vehicles are relatively easy to deploy and can significantly reduce air pollution.
Elon Musk and Tesla recently unveiled a new hydrogen fuel cell engine for electric vehicles. This hydrogen battery engine will be the most powerful car engine in the world. Hydrogen fuel cells are an excellent solution for sustainability.
These hydrogen-fueled vehicles are more expensive to obtain, mainly due to the scarcity of hydrogen stations for vehicles.
Fuel cell for power generation
Conventional large-scale power plants use non-renewable fuels with sufficient negative economic and environmental impact. Fuel cell systems are excellent candidates for small-scale distributed power generation.
Fuel cells can provide combined heat and power to commercial buildings, hospitals, airports, and military installations in remote locations. Fuel cells are up to 55% efficient, compared to 35% for conventional power plants.
Emission levels are sufficiently low that only CO2 and water vapor are emitted. Fuel cell systems can be added relatively easily when needed and installed wherever power is needed.
