The invention belongs to the technical field of electrocatalysis and
energy transformation, in particular to a novel membrane
electrode component available for
fuel cells, a preparation method and the application thereof. The new membrane
electrode component comprises catalyst
active component, nanometer carbon material,
carbon matrix complex,
proton exchange membrane and other components. The specific steps are as follows: pretreatment and
surface modification are carried out on the
carbon matrix, catalyst needed by the growth of the nanometer carbon material is deposited on the
carbon matrix, the
carbon source is used for growing the nanometer carbon material on the carbon matrix, purification treatment and
surface modification are carried out on the carbon matrix-nanometer carbon material complex, the needed fuel
cell catalyst
active component is deposited on the carbon matrix-
nano carbon material, thereby obtaining the catalyst
active component, the nanometer carbon material, the carbon matrix complex, the
proton exchange membrane and other components, namely, obtaining the membrane
electrode component available for the needed
fuel cells. The structure of the membrane electrode component is more even and sequential, can obviously increase the
reaction interface of gas-liquid-
solid, accelerates the transmission of products and reactants, greatly increases the
utilization factor of the catalyst active component, significantly reduces the usage of the catalyst active component, further plays an important role in increasing the
power density and the like of the
fuel cells.
