摘要
Abstract
Foam metals exhibit excellent mass transport properties and flow distribution capabilities,having significant potential as flow field materials in proton exchange membrane fuel cells(PEMFCs).However,they suffer severe corrosion issues in acidic and high-temperature environments.To solve these problems,nickel/graphene composite coatings were prepared on the surface of nickel foam by electrodeposition in this paper.The effect of different deposition methods on the physical properties was investigated and characterized using techniques such as X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS)and scanning electron microscope(SEM).The results indicated that higher electrodeposition current density led to lower grain size and Ni(0)content.Compared to uniformly distributed coatings obtained under constant current conditions,gradient coatings prepared sequentially at 5mA/cm2 and 10mA/cm2 exhibited superior corrosion resistance in Tafel polarization tests,potential-static tests and electrochemical impedance spectroscopy.At 150N/cm2 pressure,the interfacial contact resistance(ICR)of the gradient coating was only 8.065mΩ/cm2,which met the requirements of the 2025 DOE standard.关键词
