Electrode reactions refer to the chemical reactions that occur at the electrodes where electrons are either lost or gained. The reaction where electrons are lost is called the anode reaction, and the electrode where this reaction occurs is called the anode. The reaction where electrons are gained is called the cathode reaction, and the electrode […]

Since the birth of proton exchange membrane fuel cells (PEMFCs) in the 1950s, scientists worldwide have never ceased their in-depth research on PEMFCs. This has led to significant advancements in performance, lifespan, and cost, resulting in their widespread application in transportation, portable power sources, and distributed power generation, gradually promoting the commercialization of PEMFCs. As

1. Basic Principles of Proton Exchange Membrane Fuel Cells Proton exchange membrane fuel cells, also known as polymer electrolyte fuel cells, are a type of low-temperature fuel cell that operates at relatively low temperatures (typically below 100 degrees Celsius). This makes them highly versatile in their applications, ranging from powering vehicles to providing backup power

Earlier, we introduced the development events of fuel cells. As we can see, the development of fuel cells over time has been diverse, leading to a variety of types and numerous classification methods. However, the most common classification is based on the type of electrolyte, including “proton exchange membrane fuel cells,” “alkaline fuel cells,” “phosphoric

This article will focus on the development history of fuel cells, taking you through some important events in their evolution. Discovery of Water Electrolysis The development of fuel cells cannot be discussed without mentioning William Nicholson and Anthony Carlisle. It was their proposal in 1800 to use electricity to decompose water into hydrogen and oxygen

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
