"low humidification" is a grammatically correct phrase and can be used in written English.
It is commonly used to describe the level of moisture in the air. Example: The low humidification in the desert makes it difficult for plants to grow.
Such membranes may be beneficial for proton exchange membrane (PEM) fuel cell operation at low humidification.
In this paper, the effects of using porous metal foam based bipolar plates (BPs) are investigated under practical automotive fuel cell operations with low humidification reaction gases.
Under low humidification conditions the PEMFC prototype presented better performance when fitted with the PSBFFP since it retains water in the flow field channels.
The experimental results show that both air and the hydrogen need to be humidified to ensure optimal cell performance, and too high or too low humidification temperature can cause severe non-uniform distribution of local current density.
Under low humidification, decreasing both the MPL pore diameter and the content of polytetrafluoroethylene (PTFE) in the MPL is effective to prevent drying-up of the membrane electrode assembly (MEA) and enhance PEFC performance.
Low humidification, large air stoichiometry, dry hydrogen and low operational temperature makes open-cathode proton exchange membrane fuel cells (PEMFCs) with forced-air convection, which is designed for portable applications, quite different from that used in automobile vehicles.
There was little dew condensation on cooling bags because the absolute humidity in the chamber was low without humidification.
Difficulties were recently reported with intubation in patients failing a trial of NIV delivered at high inspiratory oxygen fraction with a low level of humidification [ 6].
Fuel cell tests carried out with recast membranes showed that the best performances are seen when the anode and cathode humidification temperatures are low.
This device delivers low-flow oxygen with cold humidification.
An innovative low cost and low pressure drop humidification system based on a properly designed enthalpy wheel is presented and discussed.
