Recent Studies from CREST Add New Data to Electrolytes [High-Temperature Polymer Electrolyte Fuel Cell Using Poly(vinylphosphonic acid) as an Electrolyte Shows a Remarkable Durability]

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Electrolytes have been published. According to news reporting originating in Tokyo, Japan, by NewsRx journalists, research stated, "The development of a high-performance, durable, and less expensive membrane electrode assembly (MEA) composed of a polymer electrolyte membrane and electrocatalysts is important for developing fuel cells."

The news reporters obtained a quote from the research from CREST, "Herein, we described the design and fabrication of an electrocatalyst with carbon black, polybenzimidazole doped with poly(vinylphosphonic acid) (PVPA), and platinum nanoparticles as an electron-conducting support material, an electrolyte, and a metal catalyst, respectively. Most importantly, we used PVPA in place of phosphoric acid, which is a widely used acid dopant, as the acid dopant for both the electrocatalyst and the polymer electrolyte membrane."

According to the news reporters, the research concluded: "We reported that the use of PVPA is crucial for the high performance of the MEA because it prevented the leaching of acid molecules from the MEA, which led to high durability compared to that of the phosphoric acid-doped MEAs."
