Fuel Cell Manufacturing Using Ultrasonic Spray Technology

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

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 catalyst, strengthe

Realizing the hydrogen economy

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.

Industrial membrane of proton exchange membrane

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

Fuel Cell Carbon Paper Spraying

Fuel Cell Carbon Paper Spraying Carbon paper (carbon cloth), also known as carbon fiber paper (cloth), is a special material for fuel cell experiments, that is, gas diffusion layer, which is an indispensable item in the heart-membrane electrode assembly (MEA) of fuel cells It plays the role of a bridge between MEA and bipolar plate. Proton exchange membrane  fuel cell  is currently one of the most promising clean energy sources. The gas diffusion layer is an important part of the proton exchange membrane  fuel cell . Carbon paper is the most widely used substrate material for gas diffusion layer due to its excellent performance and relatively mature paper-making process. An aerospace university cooperated with our company to purchase UAM4000L ultrasonic precision spraying equipment from our company to do fuel cell carbon paper spraying. The spraying area is 1 1-3 3CM, covering 1-5 mg of carbon black per square centimeter. The thickness is between 0.5-6 microns. Ultrasonic Fuel Cell Coa

Fuel Cell Catalyst Layer Coating

Fuel Cell Catalyst Layer Coating The direct methanol fuel cell (DMFC) is one of the most researched proton exchange membrane (PEM) fuel cell systems. Their low operating temperature and high energy density make them an attractive alternative for the electronic device market. In spite of these advantages the adoption and commercialization of DMFC fuel cells have been slow mainly because of the high manufacturing costs of the membrane electrode assembly (MEA), the most expensive component of direct methanol fuel cells. The catalysts used in the MEA consist of either platinum or platinum alloys, which are historically expensive materials. In addition to the cost of materials, manufacturing of MEAs is still performed with techniques developed for small-scale manufacturing, resulting in high production costs. It would greatly benefit the fuel cell industry if alternative materials and cost-effective defect-free large-scale manufacturing techniques were developed for the MEA. In PEM fuel cel
