Novel membrane electrode component available for fuel cell, preparation method and application thereof

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.
