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 of pyrrole on carbon black. Platinum (Pt) nanoparticles over these composites were achieved by using microwave irradiation technique. Physicochemical characterizations of the composites were carried out by using BET, TEM, XRD and TGA techniques. Cyclic voltammetry (CV) measurements were used to determine the ex-situ electrocatalytic activity and also the degradation behaviors of the prepared catalysts. In situ PEM fuel cell performance tests were used to evaluate the effect of carbon ratio in composite material on PEM fuel cell performance. PEM fuel cell performance was increased as the carbon ratio in the composite was increased.
Ultrasonic spray fuel cell catalyst coating system can produce highly uniform, repeatable and durable coatings. Our ultrasonic spraying can well control coating properties, significantly reduce material usage, and reduce maintenance and downtime.
- Utilization> 95%
- Spraying proton exchange membrane with high uniformity and good adhesion
- Optional diameter particles flexibly optimize the through-hole property of the coating.
