The PMBI Breakthrough

The PMBI (Polymer Membrane Bipolar Interface) is a game-changer in the field of fuel cell technology. This breakthrough material is thinner than a strand of human hair, making it an ideal candidate for use in fuel cells. The PMBI is composed of a thin layer of polymer material that is infused with ions. The material is designed to facilitate the transfer of ions and electrons, while also providing a stable and durable interface.

Understanding the Challenge

The challenge of creating a pH gradient across the PMBI has been a significant hurdle in the field of materials science. The PMBI is a complex system consisting of multiple layers, each with its own unique properties and characteristics. Achieving a stable and reproducible pH gradient across this system is crucial for various applications, including drug delivery, tissue engineering, and biosensing.
