Batteries and Fuel Cells

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...
Bioplastics01:27

Bioplastics

Bioplastics derived from microbial processes present a sustainable alternative to conventional petroleum-based plastics. Among these, polyhydroxyalkanoates (PHAs), particularly polyhydroxybutyrates (PHBs), have emerged as prominent candidates due to their biodegradability and biocompatibility. These polymers are synthesized by a variety of bacteria, such as Cupriavidus necator and Pseudomonas putida, which naturally accumulate PHAs as intracellular carbon and energy reserves, especially under...
Ion Exchange01:17

Ion Exchange

Ion exchange chromatography separates charged molecules from a solution by reversibly exchanging them with mobile, or 'active', ions associated with the oppositely charged stationary phase. This method can be used to separate ions, soften and deionize water, and purify solutions. The polymers comprising the ion-exchange column are high-molecular-weight and chemically stable polymers, crosslinked to be porous and essentially insoluble. They are also functionalized with either acidic or basic...

Area of Science:

  • Polymer Chemistry
  • Materials Science
  • Electrochemistry

Background:

  • Proton exchange membranes (PEMs) are critical components in fuel cells.
  • Developing stable and conductive PEMs, particularly under low humidity, remains a challenge.

Purpose of the Study:

  • To synthesize novel poly(2-(3-sulfo)benzoyl-1,4-phenylene)-block-polynaphthalimide (PSP-b-PI) copolymers.
  • To evaluate their properties for potential use in proton exchange fuel cells (PEFCs).

Main Methods:

  • Ni(0)-catalyzed copolymerization of specific sulfonated benzophenone and naphthalimide monomers.
  • Characterization of membrane structure, hydrolytic stability, swelling anisotropy, and proton conductivity.

Main Results:

  • Successfully synthesized PSP-b-PI copolymers with microphase-separated structures.
  • Demonstrated good hydrolytic stability at 130°C.
  • Observed strong swelling anisotropy but weak proton conductivity anisotropy.
  • Achieved high through-plane proton conductivity in water and at low relative humidity.

Conclusions:

  • PSP-b-PI copolymers exhibit desirable properties for PEMs.
  • The high through-plane conductivity contributes to excellent PEFC performance, even under challenging conditions.
