Robust PID control of a PEMFC system

2010 IEEE International Conference on Control Applications, 2010
This paper proposes robust proportional -integral-derivative (PID) control for a proton exchange membrane fuel cell (PEMFC) system. We model a PEMFC as a multivariable system, and apply identification techniques to obtain the system's transfer function matrices, where system variations and disturbances are regarded as system uncertainties.

New Polymeric Binders for the Preparation and Optimization of Pt/C‐Based Electrodes for Proton‐Exchange Membrane Fuel Cells (PEMFCs)

ChemElectroChem, Volume 13, Issue 16, 18 August 2026.
This study optimizes PEMFC catalyst layers (CLs) by comparing short‐side‐chain N+125D and high‐oxygen‐permeability EIG ionomers. By analyzing ionomer–solvent interactions in water/1‐propanol mixtures through advanced physical–chemical characterization, the research ensures ink stability and homogeneous electrocatalyst distribution.
