Abstract: A method for forming a flow channel on a metal bipolar plate of a fuel cell includes: pre-treating a metal polar plate; subjecting the metal polar plate to low-temperature heating; forming a flow channel on the metal polar plate by rolling; cutting an inlet and outlet for gas and cooling liquid on the metal polar plate; performing surface treatment on the metal polar plate; bonding two metal polar plates to form a metal bipolar plate; and trimming the metal bipolar plate. The flow channel is formed by two pre-forming and one truing, and design parameters of punches and dies of the rollers used are determined by calculation models.

Abstract: Aiming at the problem of slow crystallization rate of poly(ethylene furandicarboxylate) (PEF), a preparation method for a bio-based nucleating agent for PEF and an application thereof are disclosed. In a technical solution, glycine having a bio-based source is subjected to an amidation reaction with furoic acid under the catalysis of p-toluenesulfonic acid, followed by an acid-base neutralization reaction with sodium hydroxide to obtain a bio-based nucleating agent for PEF. The bio-based nucleating agent prepared by the present disclosure can significantly accelerate a crystallization rate of PEF. Most importantly, the bio-based nucleating agent has no effect on the bio-based properties of PEF.
