Composition and Working Principle of Single Cells A proton exchange membrane fuel cell (PEMFC) is a type of fuel cell that uses a proton exchange membrane as the electrolyte. The single cell is the fundamental unit that makes up the fuel cell stack. Here are the main components and working principles of a proton exchange […]

Accurate performance characterization methods are crucial in the study of electrocatalyst performance. This article will detail several common electrocatalyst performance testing methods, including Single battery, rotating disk electrode (RDE) and rotating ring-disk electrode (RRDE) testing, cyclic voltammetry (CV), and linear sweep voltammetry (LSV). Each method has its unique advantages and applicable scope. Understanding the basic

As the world’s energy landscape undergoes transformation and the goals of “carbon peaking” and “carbon neutrality” are proposed, hydrogen energy, with the highest mass energy density and zero carbon emissions, has garnered increasing attention. Proton exchange membrane fuel cells (PEMFCs) are currently a highly promising hydrogen energy utilization technology due to their low operating temperature,

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
