▎ 摘　　要

NOVELTY - The electrode manufacturing method involves adding de-ionized water according to a KDP crystal. The KDP salt solution is used to perform ultrasonic treatment. A dried sample is added to obtain mixed solution. The mixed solution is added by the supernatant solution. A solution drip portion of a smooth plane is fixed, where the smooth plane is made of filter paper or glass slide. Washing is performed to realize de-ionized water. Graphene oxide/potassium dihydrogen phosphate composite membrane are obtained. Rotating speed of centrifugal is calculated. USE - Method for manufacturing graphene/di-hydrogen oxide composite electrode for proton exchange fuel cell battery. DESCRIPTION OF DRAWING(S) - The drawing shows a graph of a method for manufacturing graphene/di-hydrogen oxide composite electrode.
