The use of fuel cell technology in various industries has been increasing in recent years, with its advantages in energy efficiency and environmental impact. One of the newest fuel cell applications is air compressors, where fuel cells can power the compressors while reducing emissions and energy costs. This article will explore the concept of fuel cell air compressors, their applications, and examples of their use.

1 . What is a Fuel Cell Air Compressor?

A fuel cell air compressor is a system that uses a fuel cell to power an air compressor, which is used to compress air for various applications, such as industrial processes, transportation, and energy storage. The fuel cell converts hydrogen or other fuels into electricity, which powers the compressor motor, and the compressed air is stored in tanks or used directly for the intended application. The technology offers several advantages over traditional air compressors, such as lower emissions, reduced noise, and higher efficiency.

2 . Applications of Fuel Cell Air Compressors:

Fuel cell air compressors have various applications in different industries. Some of the most notable applications include:

Industrial Processes:

Fuel cell air compressors can be used in various industrial processes where compressed air is required for powering tools, machines, and pneumatic systems. These compressors offer several advantages over traditional compressed air systems, including higher energy efficiency, lower noise levels, and reduced emissions.

Example Product: Plug Power's Air Liquide Hydrogen Fueling Station

This system is used for refueling fuel cell electric vehicles (FCEVs) and provides compressed air for the vehicle's systems. It is designed for industrial use and can operate in extreme weather conditions. The system is powered by a fuel cell stack, which produces electricity that is used to power the compressor and other components.

Transportation:

Fuel cell air compressors can be used in transportation applications, such as FCEVs, where they can power the air conditioning systems and provide compressed air for the brakes and other systems. This technology can improve the efficiency and environmental impact of transportation systems.

Example Product: Symbio's Fuel Cell Air Compressor System for Renault Master ZE electric vans

This system provides compressed air for the van's brakes and other systems, improving energy efficiency and reducing emissions. The system is powered by a fuel cell stack, which converts hydrogen into electricity to power the compressor and other components.

Energy Storage:

Fuel cell air compressors can also be used for energy storage. The compressed air can be stored in tanks and used to generate electricity through a turbine or other energy conversion systems. This technology can improve the efficiency of energy storage systems and reduce emissions.

Example Product: Nostromo Energy's Fuel Cell Air Compressor System for Energy Storage

This system uses compressed air as a form of energy storage and can be used for backup power, grid stabilization, and other applications. The system is powered by a fuel cell stack, which produces electricity that is used to power the compressor and other components. The compressed air can be stored in tanks and used to generate electricity through a turbine or other energy conversion systems.

3 . Types of Fuel Cell Air Compressors:

Several types of fuel cell air compressors are available in the market, including centrifugal, roots, screw, and scroll compressors. Here's an overview of each type:

Centrifugal Fuel Cell Air Compressor:

Centrifugal compressors use a rotating impeller to compress air. As air flows through the impeller, it is accelerated and pushed outward by centrifugal force, creating a high-pressure zone. These compressors are ideal for high-volume, low-pressure applications.

Example Product: Xebec's H-3200 Fuel Cell Compressor

This centrifugal fuel cell air compressor is designed for refueling fuel cell electric vehicles (FCEVs). It can provide up to 1000 bar of compressed air and has a flow rate of 3200 Nm3/h.

Roots Fuel Cell Air Compressor:

Roots compressors use two rotating lobes to compress air. As the lobes rotate, air is drawn into the space between them and then compressed as the lobes move apart. These compressors are known for their durability and reliability.

Example Product: Ballard's FCgen-1020ACS Fuel Cell System

This roots fuel cell air compressor is used for backup power and other applications. It can provide up to 1.2 kW of continuous power and is designed to be compact and reliable.

Screw Fuel Cell Air Compressor:

Screw compressors use two interlocking screws to compress air. As the screws rotate, the air is drawn in and compressed as it moves along the screws. These compressors are ideal for low-to-medium-pressure applications and are known for their energy efficiency.

Example Product: Doosan Fuel Cell's PureCell Model 400 Fuel Cell System

This screw fuel cell air compressor is designed for commercial and industrial use. It can provide up to 400 kW of power and has a high energy efficiency rating of up to 60%.

Scroll Fuel Cell Air Compressor:

Scroll compressors use two interlocking spiral disks to compress air. As the disks rotate, air is drawn into the space between them and then compressed as the disks move apart. These compressors are known for their quiet operation and high reliability.

Example Product: Air Squared's Scroll Fuel Cell Air Compressor

This scroll fuel cell air compressor is designed for FCEVs and other applications. It can provide up to 60 bar of compressed air and has a flow rate of up to 6 m3/h. It is designed to be compact and reliable.
