Technology to quantify the mechanical strength of fuel cell electrodes for vehicles Mechanical stability, chemical stability and thermal stability are important considerations for the durability of fuel cell membrane electrode assemblies. Quantifying the mechanical strength of the catalytic layer can provide important support for the development of highly durable CCM. The key components of the proton exchange membrane fuel cell monomer are CCM, gas diffusion layer, electrode plate and seal. Among them, the catalytic layer of the vehicle fuel cell CCM is composed of a Pt or Pt alloy catalyst, a supporting carbon carrier and an ionomer. The mechanical strength of the proton exchange membrane fuel cell electrode (or catalytic layer) is mainly determined by the ionomer. The ionomer is not only an adhesive connecting the catalyst, but also a proton conducting carrier between the proton membrane and the active points of the catalytic layer. The durability of the electrode is an important par...
