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 cells, the catalyst layer is very thin (in the order of a few microns thick) and is too delicate to be manufactured separately from other components of the cell. This layer is usually formulated as liquid ink and can be deposited by a variety of coating techniques. Among these techniques, coating the catalyst layer directly on the PEM exhibits best performance and durability, in addition to having the fewest manufacturing steps.

Fuel Cell Catalyst Layer Coating systems are particularly suitable for these challenging applications by creating highly uniform, repeatable and durable coatings. From R&D to production, our anti-clogging technology can better control coating properties, significantly reduce material usage, and reduce maintenance and downtime. Ultrasonic spraying of other metal alloys, including platinum, nickel, iridium and ruthenium-based fuel cell catalyst coatings of metal oxide suspensions, can be used to manufacture PEM fuel cells, polymer electrolyte membrane (PEM) electrolyzers, and DMFC (direct methanol fuel). Battery) and SOFC (Solid Oxide Fuel Cell) can maximize load and battery efficiency.

Fuel Cell Catalyst Coatings

Fuel Cell Catalyst Coating 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 favourably 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. Fuel cell catalyst coating systems are particularly suitable for these challenging applications by creating highly uniform, repeatable and durable coatings. From R&D to production, our anti-clogging technology can better control coating properties, significantly reduce material usage, and reduce maintenance and downtime. Ultrasonic spraying of other metal al...

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...

The attenuation mechanism of proton exchange membrane fuel cell stack under vehicle start-up and shutdown conditions

The attenuation mechanism of proton exchange membrane fuel cell stack under vehicle start-up and shutdown conditions Open/idle speed, variable load, start and stop are the three key vehicle operating conditions that accelerate the aging of fuel cell stack materials and components. Among them, the main reason that affects the durability of the fuel cell under startup and shutdown conditions is the high interface potential difference caused by the hydrogen/air interface. This article shares the attenuation mechanism of fuel cell life under startup and shutdown conditions. Start-up and shutdown is a special condition that triggers abnormal fuel cell reactions. The main reason for accelerating fuel cell degradation is the high cathode interface potential difference (up to 1.5V) caused by the anode hydrogen/air interface. Under startup and shutdown conditions, the carbon support that constitutes the main framework of the catalytic layer will be severely corroded, which will affect the Pt ca...
