Diagnosing Improper Membrane Water Content in Proton Exchange Membrane Fuel Cell Using Two-Dimensional Convolutional Neural Network

Energies, 2022
In existing proton exchange membrane fuel cell (PEMFC) applications, improper membrane water management will cause PEMFC performance decay, which restricts the reliability and durability of PEMFC systems.

New PEMFC behaviour law [PDF]

The European Physical Journal Applied Physics, 2011
This paper presents a new steady state model which contains fewer polarisation curve fitting parameters compared to other semi-empirical models. The established model is also defined at no load operation and can be fitted perfectly to the static polarisation curve for a wide range of cell currents.

Improved Semi-empirical Model of Proton Exchange Membrane Fuel Cell Incorporating Fault Diagnostic Feature

Journal of Modern Power Systems and Clean Energy, 2021
The membrane water content of the proton exchange membrane fuel cell (PEMFC) is the most important feature required for water management of the PEMFC system. Any improper management of water in the fuel cell may lead to system faults.

Harnessing Controlled Dealloying-Support Coupling for Ultrastable PtNi Catalysts in PEMFC Applications. [PDF]

Angew Chem Int Ed Engl
A controllable alloying–dealloying strategy constructs PtNi core–shell nanoparticles confined within an N‐doped carbon framework. Selective ammonia‐assisted dealloying forms a Pt‐rich shell while immobilizing Ni as Ni–N/C moieties, synergistically stabilizing the catalyst.
