The phrase “constantly working batteries” is frequently used to describe fuel cells. They use electrolytic reactions in a similar way to conventional batteries, but because the chemicals are continuously replenished, they do not discharge like conventional batteries.
The two fuels, oxygen and hydrogen, result in the production of water (and heat). The “fuel electrode” receives the hydrogen, which is then oxidised into H+ ions. The oxygen is supplied to the “air electrode,” where it reacts with the electrolyte’s water to form OH- ions.
In the electrolyte in-between the two electrodes, both of those ions come together to make water.During this process, the electrons taken from the hydrogen are taken into a external electric circuit before returning to the cathode to form the OH- ions
The Brazil Fuel cell vehicle market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2026, registering a CAGR of XX% from 2022 to 2027.
Launch of First Fuel Cell Bus in Brazil.The bus utilises a hybrid technology that combines high-power batteries with hydrogen fuel cells. On the hydrogen cell alone, it can travel 300 kilometres, and an additional 50 kilometres on its batteries.
In the neighbourhoods surrounding Sao Paulo, the bus transports people. The project received support from the World Bank, the United Nations Development Program, and other national and international organisations.
The bus is “completely clean” and just emits water vapour. Traditional buses emit damaging carbon dioxide and other pollutants when they run on diesel fuel. Diesel fuel is used by the majority of buses worldwide. In São Paulo, diesel cars are the biggest source of air pollution.
