I. Introduction: With the continuous development of global transportation, the consumption of petroleum by countries around the world is increasing. Among these consumptions, the large-scale popularization of internal combustion engines has led to severe atmospheric pollution and exacerbated the greenhouse effect. To address this issue, the United Nations, the European Union, and the IPCC have […]

Using laser welding to join hundreds of bipolar plates is an advanced technology that is increasingly being adopted by fuel cell manufacturers.Laser welding uses a high-energy-density laser beam to rapidly melt the contact surfaces of two metal plates and completely fuse them together to form a strong weld. This technology demonstrates exceptional advantages in industries

What is graphite bipolar plate？ A graphite bipolar plate is a crucial component in fuel cells, particularly in proton exchange membrane fuel cells (PEMFCs) and solid oxide fuel cells (SOFCs). It is responsible for providing the surface for electrochemical reactions, enabling the flow of electrons, and serving as a separator between individual fuel cell units.

Summary:The development of Proton Exchange Membrane Fuel Cells (PEMFCs) is showing great potential to become a clean, efficient, and reliable power source. Bipolar plates, one of the key components of PEMFCs, play a critical role by providing electrical connections, delivering reactant gases, dissipating reaction heat, and removing byproducts. However, they are also a significant contributor

As technology continues to advance and international policies drive progress, new energy vehicles are becoming increasingly popular, including hybrid cars, all-electric vehicles, and even hydrogen fuel cell vehicles, which, while not yet common, are slowly gaining attention. If you’re unfamiliar with hydrogen fuel cell vehicles, the following introduction will help you understand them better. Let’s

Fuel cell vehicles indeed hold promise for the future of transportation, but their widespread adoption might take longer than anticipated. What is a fuel cell？ A fuel cell is a device that generates electricity through an electrochemical reaction between a fuel, typically hydrogen, and an oxidizing agent, usually oxygen from the air. Unlike traditional combustion

The Evolution of Electric Vehicles Over the past century, electric vehicles (EVs) have evolved from a mere concept into a revolutionary force shaping the future of transportation. Despite their humble beginnings in the late 19th and early 20th centuries, early EVs faced numerous challenges, including limited range, lengthy charging times, and inadequate performance. However, with

Bipolar plates, often referred to as current collectors, are indispensable components within fuel cell technology. Positioned between membrane electrode assemblies and sealing components, these plates play a multifaceted role that is essential for the efficient operation of fuel cells. Functionally, bipolar plates serve as critical links within the fuel cell stack, performing a range of

What are metallic bipolar plates? In the realm of proton exchange membrane (PEM) fuel cells, metallic bipolar plates play a pivotal role in facilitating efficient energy conversion. Serving as crucial components within fuel cell stacks, these plates contribute significantly to the conductivity and longevity of the system. Bipolar plates for PEM fuel cells act as
