Fuel Cell Coatings |
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. |

DOVE TAIL GAS ASSISTED SPRAY ATTACHMENT |
Ultrasonic spray deposition solution is delivered to the ultrasonic nozzle, creating a spray with uniform-diameter droplets. The spray is focused onto the substrate using nitrogen as the carrier gas. With the Sonaer dove tail spray shaper, droplets are atomized with the nozzle and the carrier gas is used to spreads the uniform droplets over a wider area. Controlling the flow of solution, carrier gas and exposure of droplets, uniform material thickness is easily deposited on the substrate. |
PIN POINT SPRAYING WITH THE PPSAS ATTACHMENT |
This product attaches directly around the atomizer nozzle and a small gas flow is used to focus droplets to a pin point. The nozzle works with liquid through the center orifice and the gas surrounds the droplets making them sharp. |
FLAT SPRAY ATTACHMENT FOR COATING LARGE AREAS ROBOTICALLY |
Sonaer flat spray attachment provides coverage in a rectangular area. The shaper spreads droplets in a consistent thin uniform direction with very little overspray. Thickness is nano to microns and is adjusted by the scientist for the application being developed. |
GAS ASSISTED SPRAY ATTACHMENT |
Sonaer wide vortex spray attachment uses a small gas pressure to coat large areas with low volume of droplets. Droplets are dispersed over a wide area and provide a thin uniform coverage. |
