Preparation method of oxygen-loss type oxide ceramic spherical powder, oxygen-loss type oxide ceramic spherical powder and fuel cell electrolyte film
The invention provides a preparation method of oxygen-loss type oxide ceramic spherical powder, the oxygen-loss type oxide ceramic spherical powder and a fuel cell electrolyte film, and relates to thetechnical field of fuel cells. The preparation method comprises the following steps: carrying out a high-hydrogen-concentration induction plasma process on oxide ceramic powder to obtain oxygen losstype oxide ceramic spherical powder, wherein the high hydrogen concentration means that the hydrogen flow in the plasma gas accounts for more than or equal to 30% of the total flow of the plasma gas.The oxygen loss type oxide ceramic spherical powder is obtained through the preparation method, and the fuel cell electrolyte film is obtained through low-pressure plasma spraying. Oxide ceramic powder is conveyed into induction plasma flame flow with high hydrogen concentration, and the oxygen loss type oxide ceramic spherical powder with high compactness, high sphericity degree, high flowabilityand high impact force is obtained through the processes of melting, reducing and cooling. The powder is easier to melt in plasma spraying flame flow, the controllability and operability of a sprayingprocess are improved, and the performance of an electrolyte film is improved.
