Hydrogen Fuel Cells for Climate Neutrality
Fuel cells are key to climate neutrality, powering vehicles and machinery with zero emissions by converting hydrogen into electricity. This technology reduces fossil fuel dependence and cuts greenhouse gases. Key components of fuel cell include the fuel cell stack, hydrogen storage, and power control unit. Depending on the application several types of fuel cells can be utilized.
Proton Exchange Membrane Fuel Cell (PEM)
The PEM Fuel Cell generates electricity from hydrogen and oxygen through a chemical reaction. It is considered a zero-emission technology since the only byproducts are water and heat. Due to it’s high power density, low running temperatures and pressures and quick start-up time the PEM Fuel Cell is an ideal solution for on and off highway applications.
Phosphoric Acid Fuel Cell (PAFC)
Phosphoric Acid Fuel Cells (PAFC) utilize liquid phosphoric acid as an electrolyte to produce electricity from hydrogen, offering robust performance and long operational life. Although bulkier and less power-dense than PEM fuel cells, PAFCs are well-suited for larger mobile machinery and stationary power applications due to their higher tolerance to fuel impurities and reliable efficiency.
Solid Oxide Fuel Cell (SOFC)
Solid Oxide Fuel Cells (SOFC) operate at high temperatures using a ceramic electrolyte to convert a variety of fuels into electricity with high efficiency and fuel flexibility. Their suitability for electric trucks, buses, and mobile machinery lies in their potential for high electrical efficiency and the ability to utilize alternative fuels like natural gas, although their long startup times and thermal management needs pose practical challenges for on-the-go applications.
Efficiency
Performance
The performance of hydrogen fuel cells, crucial for zero emission vehicles and renewable energy systems, significantly depends on the purity of hydrogen, the quality of air and the thermal management of the fuel cell system. Contaminants can degrade catalysts and membranes, reducing efficiency. Utilizing high-quality hydrogen fittings, cathode air filters and fuel cell humidifiers is crucial for optimal operation and longevity.
Durability
Durability in hydrogen fuel cells relies on advanced materials and engineering, including the use of hydrogen compatible seals and advanced cooling systems, to withstand operational stresses and prevent degradation. Regular maintenance, thermal management, and minimizing catalyst poisoning are essential for prolonging their operational life and ensuring consistent, efficient energy output.
Safety
Leak Rate
Leaks in fuel cells can result from seal deterioration, material fatigue, or improper assembly. Preventative measures include regular maintenance checks, using high-quality materials and components, ensuring precise assembly, and adopting advanced sealing technologies, such as hydrogen seals and hydrogen fittings, to maintain system integrity and safety.
Embrittlement
Hydrogen embrittlement in fuel cells can lead to material degradation and structural failure. Mitigating this involves using hydrogen-resistant alloys and employing proper design and preventive maintenance strategies to ensure the longevity and safety of fuel cell systems.
