Market Overview

The global fuel cell in aerospace and defense market size was valued at USD 2.44 billion in 2025 and is projected to grow from USD 2.81 billion in 2026 to USD 8.71 billion by 2034, registering a CAGR of 15.18% during the forecast period from 2026 to 2034. North America dominated the fuel cell in aerospace and defense market with a market share of 42% in 2025.

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.

Segmental Analysis

The global fuel cell in aerospace and defense market is segmented by product and application.

Based on the product, the global market is bifurcated into Proton Exchange Membrane Fuel Cell (PEMFC) and Solid Oxide Fuel Cell (SOFC).

The PEMFC segment dominates the global market and is expected to grow significantly over the forecast period. PEMFC requires pure hydrogen, oxygen, and water for its function. It operates at a comparatively lower temperature of around 80°C, making it eligible for quick start and less prone to wearing of system components. As a result, PEMFC is more durable than other product types. It also provides advantages such as low weight and volume compared to other fuel cell types. In addition, PEMFC is extensively used for transportation applications in the aerospace industry due to its efficiency, compactness, temperature range, and durability. According to Honeywell Aerospace, air-cooled PEMFC is optimal for aerospace applications due to its superior thermal management, lighter balance of plant, shortened stack service life, and restricted integration flexibility.

PEMFC is also utilized in various defense applications, including military vehicles and drones. The PEMFC product segment has experienced significant growth and recognition due to the rising demand for fuel cells in unmanned aerial vehicles (UAVs), which has resulted in increased sales and prominence.

Solid oxide fuel cells produce electricity from hydrogen, natural gas, and other renewable fuels. Therefore, the power generated does not result in the emission of environmental pollutants in most cases. Solid oxide fuel cells produce power through a chemical reaction, generating little or no noise. In addition, the integration of fuel cell vehicles or other mobile applications can mitigate noise levels during driving. Solid oxide fuel cells have significant growth opportunities in stationary applications in residential and commercial sectors. Bloom Energy has emerged as a major company that utilizes SOFC in fuel cell-based power generation.

Based on application, the global market is segmented into aerospace (commercial aircraft and rotorcrafts) and defense (military drones/UAVs and military vehicles).

The commercial aircraft segment owns the highest fuel cell in aerospace and defense market share in the aerospace segment. Fuel cells powered by hydrogen are installed on aircraft with a passenger capacity of up to 20. Nevertheless, aircraft manufacturers are currently conducting feasibility studies for larger commercial aircraft. For instance, in January 2021, Airbus established the ZEROe program, which consists of six eight-bladed pods powered by hydrogen fuel cells and affixed beneath the wing of a large commercial aircraft. The system comprises a propeller, electric motors, fuel cells, an LH2 tank, a cooling system, and auxiliary equipment.

In addition, in September 2020, hydrogen-electric engine manufacturer, ZeroAvia completed the world's first commercial flight powered by fuel cells. The efficiency of hydrogen fuel cells in commercial aircraft reached up to 60% compared to 25% in a standard combustion engine. In February 2021, Slovenia's Pipistrel Aircraft announced plans to launch lightweight, hydrogen fuel cell-powered 19-seat hybrid aircraft to revolutionize the commuter category segment. Such factors are expected to augment the demand for fuel cells in the commercial aircraft segment over the forecast period.

The military vehicles segment accounted for a dominating market share in the defense segment. A military drone is a cutting-edge system in the defense industry that has gained much popularity in applications such as surveillance and monitoring. The adoption of fuel cells and military unmanned aerial vehicles to decrease the dependency on imported oil is expected to emerge as a key trend in the market. Despite the growing technological advancements, the development of lightweight UAVs is a market challenge. It has been observed that a typical UAV's power source and fuel typically account for about 35%–65% of the vehicle's weight, whereas for small UAVs, it is closer to 38%–40%. However, manufacturers are strategizing to cope with the market challenges. For instance, in May 2021, the South Korean Air Force collaborated with Doosan Mobility Innovation, Inc. to purchase hydrogen-powered fuel cell drones to boost its surveillance capability.
