A fuel cell is an electrochemical system that converts the chemical energy of a fuel, commonly hydrogen, and an oxidizing agent, typically oxygen, into electrical energy through two redox reactions. Fuel cells differ from most batteries because they require constant fuel and oxygen (typically from the air) to sustain the chemical reaction. In contrast, chemical energy originates from already present substances in a battery. Fuel cells can continuously generate electricity when fuel and oxygen are provided.
In 1838, Sir William Grove developed the first fuel cells. Following the 1932 invention of the hydrogen–oxygen fuel cell by Francis Thomas Bacon, the first commercial use of fuel cells occurred almost a century later. The alkaline fuel cell, commonly called the Bacon fuel cell in honor of its inventor, has been employed by NASA space programs since the mid-1960s to produce electrical power for satellites and space capsules. Since then, fuel cells have been utilized in numerous additional applications. Fuel cells are utilized as primary and backup power sources for commercial, industrial, and residential structures in remote or inaccessible locations.
The aerospace sector was responsible for 2.0% of global CO2 emissions in 2020, according to the Air Transport Action Group. In 2020, the International Air Transport Association (IATA) observed a notable decline in air traffic, primarily attributed to the impact of the COVID-19 pandemic. Consequently, stakeholders within the aviation industry have actively pursued initiatives to reduce carbon emissions and achieve decarbonization in this sector. Countries such as Germany, the U.K., the U.S., and France have formulated their National Hydrogen Strategies focusing on decarbonizing transportation and aviation sectors. For example, Airbus focuses primarily on using hydrogen fuel cells and sustainable aircraft fuels (SAF) to decarbonize its business in commercial aircraft.
Additionally, direct combustion of hydrogen in the turbofan or turboprop engine is used as one of the technologies to decarbonize the aviation industry. Companies across the globe are collaborating among themselves to accelerate the process of decarbonization in the aviation industry. For instance, TotalEnergies and Safran entered into a strategic partnership agreement in September 2021 to jointly develop commercial and technical solutions for the decarbonization of the aviation industry. The abovementioned factors are expected to propel the growth of decarbonization in the aerospace industry over the forecast period.

Implementing suitable policies that will help manufacturers achieve economies of scale is expected to play a key role in making this technology economically viable.
In addition, electrolysis is an extremely inefficient process for hydrogen production and consumes a lot of energy. Therefore, hydrogen produced is required to be compressed and then filled in a vehicle tank. This process makes fuel cell electric vehicles (FCEVs) cost-ineffective, restricting market growth.
Aerospace and defense spending continues to rise despite the COVID-19 pandemic, which resulted in a 66% decline in passenger air traffic in 2020. Global defense spending is expected to grow by 2.8% in 2021 as countries continue to strengthen their militaries due to geopolitical tensions intensifying in light of the global pandemic. Major countries have announced to increase their military spending despite the economic impact on fiscal deficits due to the COVID-19 pandemic.
Furthermore, China announced a military budget of USD 178.2 billion in May 2020, 6.6% more than the previous year. Japan also announced a budget of USD 51.6 billion, nine times more than the previous year. Similarly, zero-emission-powered fuel cells deliver high efficiency and are more reliable for long-distance flights and military surveillance. Therefore, increasing aerospace and defense spending allows fuel cell technology to evolve and penetrate the market.
