Composition of Fuel Cell System

Composition of Fuel Cell System Fuel cell power generation requires a relatively complex system. In addition to fuel cell stacks, it also includes fuel supply subsystems, oxidant supply subsystems, water and heat management subsystems, and electrical management and control subsystems. The main system components include air compressors. Machine, humidifier, hydrogen circulation pump, high-pressure hydrogen cylinder, etc. These subsystems and fuel cell stacks (or modules) form a fuel cell [...]

What is Semiconductor

What is Semiconductor Before the discovery of semiconductors, people believed that materials in the world could only be divided into "conductive" and "non-conductive (insulating)" according to the classification of conductivity. According to the principle of "mutual independence and complete exhaustion" in the classification method, this is a very perfect classification method for materials in the world. Why does the classification of "semiconductor" still exist? In some documents, "semiconductor" [...]

Medical Conveyor Polymer Materials

Medical Conveyor Polymer Materials In minimally invasive interventional medical devices, stents and covered stents are commonly used. These devices and conveyors constitute a complete interventional medical device. After the transporter is transported, it has to complete the disposal process of withdrawing from the body after placement, so it is usually a disposable appliance. Even so, the performance of the conveyor will directly affect the smoothness of the operation [...]

Introduction to Fuel Cell System

Introduction to Fuel Cell System Fuel cell system is the most basic and core part of fuel cell vehicles. The biggest difference between fuel cell vehicles and power battery vehicles is the use of hydrogen-oxygen reaction to generate electricity. The fuel cell system is mainly composed of a stack, a fuel processor, a power regulator, and an air compressor. Each system component has its unique key technology, among [...]

Implantable Polymer Materials

Implantable Polymer Materials In minimally invasive interventional therapy devices, polymer materials can be used to meet the needs of carriers that need controlled release systems, such as covered stents, embolic agents, biodegradable stents and therapeutic drugs. Such devices usually coexist with the human body for a long time after implantation. Therefore, the polymer materials used shall ensure good antithrombotic property, excellent compatibility, stable physical and chemical properties and [...]

How Fuel Cells Work

How Fuel Cells Work The principle of fuel cell power generation is similar to that of primary batteries or secondary batteries. Hydrogen oxidation and oxygen reduction reactions occur on both sides of the electrolyte diaphragm, and electrons do work through an external circuit, and the reaction product is water. However, unlike the primary battery, the reactants in the fuel cell are not pre-stored inside the battery, but when [...]

Classification of Transistors

Classification of Transistors In the past 100 years, during the development of semiconductor transistors, pioneering scientists and engineers have constantly tried various device structures and device materials to meet the requirements of integrated circuit characteristics in different fields. Various semiconductor devices are produced. Semiconductors are inherently abstract and elusive. The various names and abbreviations of semiconductors also make semiconductors more unpredictable, which brings many troubles to the electronics [...]
