What is solid oxide fuel cell?

The Solid Oxide Fuel Cells came to existence in the 20th century and were employed in all kinds of inventions and technologies. They have their distinctive style and can be used in variety of applications like in space and satellites, capsules in vehicles like buses or boats, mainly for the purpose of generating the primary power or else acts as a backup power for buildings. In general, a fuel cell is a device that initiates electricity through a chemical reaction. The main initiation of this cells is to produce the electrical current, that may assist in powering the electric vehicles or for irradiating a light bulb.

How they Work?

Solid oxide fuel cells comprise of three things mainly: an electrolyte, an anode, and a cathode. Fuel and air get transformed into electricity, with the help of a chemical reaction. Since solid oxide fuel cells are high temperature cells, warm air arrives the cathode and steam get blended to form a reformed fuel. This renewed fuel is key to the reaction process because it attracts oxygen atoms from the cathode. Then the oxygen and reformed fuel combine to form electricity. This procedure can be repeated as many times as possible as long as there is fuel, air and heat. 

Applications of Solid Oxide Fuel Cells (SOFC):

Residential/Combined Heat & Power: SOFCs gets well matched with the stationary power generation for homes and businesses. Their high temperatures make them predominantly efficient for Combined Heat and Power (CHP) systems, as waste heat can be put to good use for heating and cooling.

Industrial: Larger scale systems can also be employed for industrial applications, from charging the entire factories to keeping machinery cool. Significant amount of power is saved by CHP over integrated power generation and separate heat generation. Fuel cells proposes more efficient energy conversion than power stations and eliminate energy losses that occur when electricity travels over power lines.

Transportation: Fuel cells can charge up vehicles with as little as zero tailpipe emissions. Fuel cells are previously being used in large fleets where wide spread use helps to offset the initial capital cost, and where fueling services can be achieved at a central depot. They have found uses in ships, buses and even aircraft.

Energy Storage: SOFCs can function in opposite mode, as a Solid Oxide Electrolyser Cell (SOEC), spinning the energy and water back into hydrogen. By consuming the energy from renewables when they are not serving into the grid, fuel cells can run in reverse, generating hydrogen gas through electrolysis. Hydrogen permits a huge amount of energy to be stored for long periods, so the energy from the sun could be used in summer to produce hydrogen, which develops a fuel source in winter. 

Final Words:

Fuel cells are frequently proving to be the best combination of proficiency, resiliency, and sustainability in the substitute energy generation landscape, and hence are the chief power generation technology for businesses and communities.
