Ultrasonic Spray Technology for Fuel Cell Applications Ultrasonic spray coating technology has only been used for fuel cell applications in recent years. It has been demonstrated that ultrasonic spray coating is an effective way to reduce platinum loading for fuel cells. The opti-mum catalyst ink formula and platinum loading are dependent on operating conditions. In terms of cost, opti-mum platinum loadings must be considered alongside thecost of other [...]

Ultrasonic Spray Coating for Proton Exchange Membrane Fuel Cell Ultrasonic Spray Coating for Proton Exchange Membrane Fuel Cell - Cheersonic Climate change and global warming have become urgent topics for green energy and carbon emission reduction. Proton exchange membrane fuel cells (PEMFC) have become a promising power source in the future due to their high power density, high efficiency, no harmful emissions, high-quality power supply, scalability and fast [...]

Carbon Nanotubes Carbon nanotubes (CNTs) are a subject of great interestgiven their unique structure and excellent properties. They offer potential applications in electronic devices, catalysts, sensors, field-emission devices and hydrogen-storage media. The size and morphology of CNTs enable them to bea suitable catalyst support, in which active metal particlesmay disperse on the external walls or be encapsulated in theinterior of the nanotubes. The metal particles on the externalwalls [...]

Polypyrrole as a Conductive Polymer Polypyrrole as a Conductive Polymer - Conductive Polymer Coating - Cheersonic In the last years new carbon and/or composite materials have been suggested as support for PEM fuel cell catalysts to improve the stability of the catalysts. In the present study, polypyrrole (PPy) was used as conducting polymer and PPy/carbon composites having different carbon ratios were synthesized by in situ chemical oxidative polymerization [...]

Air-breathing PEM Fuel Cells Newly developed portable electronics require power sup-plies with a higher energy density and longer operation time. As a substitute for currently used batteries, fuel cells are beingconsidered based on their potential to fulfil these requirements. Among the various types of fuel cells, the polymer electrolyte membrane fuel cell (PEMFC) has many advantages for portable electronics such as a low operating temperature, fast response, design [...]
