Abstract：Porous nickel plates with porosity of 22.2%-52.4% were prepared by powder rolling technology using
ammonium bicarbonate（NH4HCO3）as pore-making agent. The effect of pore-forming agent content on microstructure
and properties of porous nickel plate was studied. The results show that with the increase of pore-forming
agent content, the porosity of porous nickel plate increases gradually, the relative permeability increases gradually,
and the tensile strength decreases gradually. When the content of pore-forming agent is 20%, the porosity of porous
nickel plate is 40.7%, the relative permeability coefficient is 10.79 m3/(h·kPa·m2), and the tensile strength is
135 MPa. When the content of pore-forming agent is 40%, the porosity of porous nickel plate is 52.4%, the relative
permeability coefficient is 41.0 m3/(h·kPa·m2), and the tensile strength is reduced to 51 MPa.
