  Hydrogen Fuel Cell Commercial Vehicle Problems Hydrogen Fuel Cell Commercial Vehicle Problems. What keeps the cost of hydrogen fuel cell commercial vehicles high? Seek ideas to solve difficult problems At present, many countries in the world have regarded hydrogen fuel cell technology as an important part of future energy strategy deployment. Solving the cost problem has become an important foundation for promoting the development of hydrogen  fuel cell  commercial vehicles. High cost becomes resistance In recent years, the development of hydrogen fuel cell vehicles has become the focus of attention in the industry. However, there are still many problems to be solved whether it can be truly implemented and applied on a large scale, one of which is the high cost. The purchase cost of a hydrogen fuel cell bus is more than twice that of a petrol vehicle and a pure electric vehicle. Cost is the key to determining whether hydrogen fuel cell commercial vehicles can develop co...

  New Energy Heavy Truck Development In recent years, new energy heavy truck development, in the field of heavy trucks with higher requirements for new energy power systems, hybrid, pure electric and  fuel cell technologies  have continued to develop, new application scenarios have been continuously developed, and demand has continued to grow. New energy heavy trucks have already shown development potential. 1 Technical status of hybrid heavy trucks So far, the development of new energy vehicle technology, hybrid technology is the most mature, and the increased cost is the smallest. At present, the hybrid power system includes three types: series, parallel and hybrid. The parallel hybrid power system is composed of a traditional internal combustion engine system and a motor drive system. The engine, motor, and transmission are combined to form different power modes, which can be applied to a variety of different driving conditions and have high energy utilization. At pres...

Fuel Cell Manufacturing Using Ultrasonic Spray Technology A variety of fuel cells utilize catalysts at both the anode (to oxidize fuel and convert it to protons/hydrogen cations and electrons) and the cathode (convert hydrogen cations and oxygen to water), often precious metal, nanocarbon, or other nanomaterial-based. Doped carbon nanotubes and core-shell metallic or composite nanoparticles are two examples of such. Such catalyst materials need first to be synthesized and then coated onto electrode and/or membrane surfaces for use in fuel cells. Solid oxide fuel cells (SOFCs) that do not utilize catalyst coatings are also of interest. Cheersonic high-temperature nozzles, nebulizers, and particle generators can be used for fuel cell catalyst nanomaterial synthesis via chemical vapor deposition and/or spray pyrolysis techniques. Moreover, Cheersonic can custom manufacture AACVD and spray pyrolysis systems for fuel cell catalyst synthesis, based on customer goals and requirements, whether...

MEA Activation Mechanism And Type The core component of the  proton exchange membrane fuel cell  (PEMFC) is the  membrane electrode . MEA (Membrane Electrode Assembly), its performance greatly determines the performance of PEMFC. The performance of several main components of MEA (electrocatalyst, proton exchange membrane and diffusion layer) and the preparation process of MEA certainly have a great influence on its performance, but in order to enable PEMFC to quickly reach its optimal state and Work performance. Before the MEA is prepared and assembled into a fuel cell stack for normal test operation, the MEA is usually activated. In addition, for PEMFC performance degradation caused by long-term parking for a period of time, the performance of PEMFC can also be restored to a certain extent through MEA activation. Study On Activation Of Membrane Electrode The activation of PEMFC can increase the activity of the platinum catalyst, increase the utilization rate of the catal...

Realizing the hydrogen economy Realizing the hydrogen economy – Coating Catalysts – Cheersonic Although less efficient than electric batteries, today’s hydrogen fuel cells compare favorably with internal combustion engine technology, which converts fuel into kinetic energy at roughly 25 per cent efficiency. A fuel cell, by contrast, can mix hydrogen with air to produce electricity at up to 60 per cent efficiency. A fuel cell works much like an electric battery, converting chemical energy into electrical energy using the movement of charged hydrogen ions across an electrolyte membrane to generate current. There they recombine with oxygen to produce water – a fuel cell’s only emission, alongside hot air. Although less efficient than electric batteries, today’s fuel cells compare favorably with internal combustion engine technology, which converts fuel into kinetic energy at roughly 25 per cent efficiency. A fuel cell, by contrast, can mix hydrogen with air to produce electricity at up t...

Industrial membrane of proton exchange membrane Industrial membrane of proton exchange membrane – Cheersonic Proton exchange membrane fuel cell (PEMFC) has the advantages of light weight, high efficiency, high specific power, high energy conversion rate, low starting temperature and environmental friendliness. It is an ideal power source for new energy vehicles and portable electronic products. Membrane electrode (MEA) is the core component of proton exchange membrane fuel cell, mainly composed of gas diffusion layer (GDL), catalytic layer (CL) and proton exchange membrane (PEM). Proton exchange membrane (PEM) is one of the core components of PEMFC, which can transfer protons but insulate electrons, which directly affects the performance and service life of fuel cells. A PEM with good performance must meet the following conditions: 1) Strong proton conductivity; 2) Good mechanical properties and not easy to deform; 3) High thermal and electrochemical stability. At present, the membra...
