Modelling of Humidity Dynamics for Open-Cathode Proton Exchange Membrane Fuel Cell
Published 2021-08-01“…The durability and output performance of a fuel cell is highly influenced by the internal humidity, while in most developed models of open-cathode proton exchange membrane fuel cells (OC-PEMFC) the internal water content is viewed as a fixed value. Based on mass and energy conservation law, mass transport theory and electrochemistry principles, the model of humidity dynamics for OC-PEMFC is established in Simulink<sup>®</sup> environment, including the electrochemical model, mass flow model and thermal model. …”

Assessment of Lower Sakarya River Water Quality in Terms of Irrigation Water
Published 2019-07-01“…Different physical-chemical properties of water quality data belonging to 3 stations operated by State Hydraulic Works (DSI) on Sakarya River were evaluated in terms of national and international water quality standards. On the basis of these standards, irrigation water quality was interpreted by using evaluation criteria such as Electrical conductivity (EC), and Total Hardness (TH) values, Schoeller Diagram, Sodium Adsorption Rate (SAR), Sodium percentage (% Na), Magnesium Ratio (MR), Potential Salinity (PS) and Kelley index (KI).…”

An aqueous H+ permeation pathway in the voltage-gated proton channel Hv1.
Published 2010“…Our results indicate that Hv1 most likely forms an internal water wire for selective proton transfer and that interactions between water molecules and S4 arginines may underlie coupling between voltage- and pH-gradient sensing.…”
