Performance characteristics

 

Application

Hydrogen fuel cells have the advantages of zero pollution (the only products produced are water and heat), low noise (operating noise is about 55 decibels), and high efficiency (power generation efficiency exceeds 50%). They are currently widely used in aerospace, aviation, new energy vehicles and other fields.  

The electrode is the site of electrochemical reactions where fuel oxidation and oxidant reduction occur, and is a key structural component of hydrogen fuel cells.

Emerging Thin-Layer Electrode Preparation Methods: The novel thin-layer electrode manufacturing process involves coating the catalyst ink onto a transfer substrate and then drying it to form a three-phase interface. The substrate is then hot pressed to bond with the proton exchange membrane (PEM). Finally, the transfer substrate is removed, thereby transferring the catalyst layer from the substrate to the PEM.   This process imposes stringent performance requirements on the transfer substrate, including temperature resistance, non-stick surface properties, flatness, and dimensional stability during hot pressing.  

Our films excel in these aspects, perfectly meeting the stringent requirements of thin-layer electrode processing technology and are ideal transfer substrates for electrode manufacturing processes.
