Membrane moisture transfer in fuel cell humidifiers
2011High system cost and large size are two barriers preventing mainstream commercial viability of proton exchange membrane fuel cells. These barriers can be addressed by (a) improving water management in the cell for a higher power density at lower cost and (b) reducing the cost and size of balance of plant components.

Modelling of water-to-gas hollow fiber membrane humidifier
Chemical Engineering Science, 2018Abstract A microscopic mathematical model is developed for membrane based water-to-gas humidification by rigorously accounting for phase equilibrium between the membrane and water phases as well as membrane and gas phases in addition to the coupled heat and mass transfer occurring across the membrane.

Modeling and Analysis of Membrane Humidifiers for Fuel Cell Applications
Dynamic Systems and Control, Parts A and B, 2004Maintaining proper membrane humidity is crucial to ensure optimal operation of a polymer electrolyte membrane fuel cell, which can be achieved by adding a humidifier to the fuel cell system. A membrane-type humidifier system using the fuel cell exhaust gas to humidify the dry inlet air is studied in this paper.

Internally humidified proton exchange membrane fuel cell
Intersociety Energy Conversion Engineering Conference, 1994To simplify a proton exchange membrane fuel cell (PEMFC) and to minimize its auxiliary subsystems, the fuel cell needs to operate at the ambient pressure requiring no external humidification. Towards that goal, a PEMFC has been developed and evaluated.

ECTFE membrane preparation for recovery of humidified gas streams using membrane condenser
Reactive and Functional Polymers, 2014Polymeric flat membranes, using Ethylene-Chlorotrifluoroethylene copolymer (ECTFE), have been made by Thermal Induced Phase Inversion (TIPS). The non-toxic solvent glycerol triacetate (GTA) has been used as solvent. The morphology of the membranes has been analyzed by scanning electron microscopy (SEM). Asymmetric microporous sponge-like membranes have
