1. a preparation method for the flow field diffusion layer of solid polymer electrolyte water electrolytic cell integral structure, is characterized in that:

  • diffusion layer and gas-liquid flow field are integral type structure, and preparation comprises the following steps;

    (1) porous material is selected to make diffusion layer substrate, by the base material diffusion layer of moulding process formation with flow field;

    Or metal-powder is shaping, form the diffusion layer substrate with flow field;

    (2) by

         1) described in the diffusion layer substrate with flow field carry out coating process, or diffusion layer substrate is annealed under vacuum or hydrogen, or carry out coating process after being annealed under vacuum or hydrogen by the diffusion layer substrate with flow field, be formed in the flow field diffusion layer of the integral structure that solid polymer electrolyte water electrolytic cell uses.
