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 for the development or production of catalyst particles, for the research lab, start-up, or experienced production facility. Cheersonic nozzles or probes may also be used for spray particle synthesis, sonochemical synthesis, or other wet-chemical synthesis techniques utilized to make catalyst materials and nanoparticles.

Cheersonic nozzles can also be used to coat electrode or membrane substrates with catalyst materials. As a consequence of synthesis, or post-synthesis, depending on the technique used, catalyst particles are often suspended, forming "inks", which then need to be coated onto appropriate electrodes or membranes for use in fuel cells. Cheersonic's ultrasonic atomizer nozzles and automated robotic coating systems can be used to accurately, precisely, and uniformly coat catalyst films and layers onto such substrates, minimizing overspray and hence minimizing waste, which is also important for device optimization, reproducibility, sustainability, and cost savings. Cheersonic develops robotic coating systems from the benchtop/research level up, allowing for scalability of processes used to create novel, "cutting-edge" fuel cell catalysts as part of a clean, sustainable energy future. Furthermore, solution- or suspension-based spraying using Cheersonic nozzles can potentially be utilized to print or coat solid oxide fuel cell materials, even if such spraying need occur over a heated substrate or in a heated environment such as an oven or furnace.

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...
