Latest Patents

One of Peiwen Li's latest patents is for a high-temperature fuel cell system featuring a laminated bipolar plate. This innovative fuel cell system includes a stack with at least one high-temperature membrane electrode assembly and a bipolar plate that is laminated with an electrically conducting layer. This design creates a structure that contains a liquid cooling chamber and gas flow channels on the outer side. The membrane of the assembly is composed of a composite of inorganic and organic proton-conducting particles, supported by a porous layer of metallic material at the anode. This patent also covers methodologies for manufacturing and utilizing such a fuel cell system, as well as an electrical generation system that employs it.

Another notable patent involves an integrated reformer, reactor, and control system designed for efficient hydrogen production from hydrocarbons. This unit is a key component of a fuel cell, utilizing a combination of a hydrocarbon auto-thermal reformer, a water-gas shift reactor, and multiple countercurrent flow heat recuperators. The design allows for the generation of hydrogen in addition to that already present in the reformate formed at the reformer. The proton-conducting membrane in this system includes an inorganic polymer with pores filled with an organic polymer, enabling operation across a wide temperature range without the need for added solvents.
