Resumen de: WO2025231966A1
Disclosed in the present invention are a titanium alloy bipolar plate with a high pitting potential and a low resistivity and a preparation method therefor. The titanium alloy bipolar plate comprises the following components in percentages by mass: 3.0-5.0% of Mo, 0.1-0.3% of Ni, 0.005-0.05% of Ru and the balance being Ti, and the total content of impurity elements (Fe, O, C, N and H) does not exceed 0.01%. According to the titanium alloy bipolar plate of the present invention, on the basis of meeting the electrical conductivity requirement, the pitting potential of the titanium alloy bipolar plate can be improved, such that the problems of a relatively poor corrosion resistance and a low hydrogen production efficiency caused due to the relatively low pitting potential of the titanium alloy bipolar plate in a service environment of a water electrolysis hydrogen production electrolytic bath are fundamentally solved.
