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.

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...
