RH Table
Uses the RH Calculation equations discussed above to create a table of dew points and relative humidities from 10% to 100% RH, for a given cell temperature.
Click here for JavaScript Calculations The JavaScript calculator will calculate a single table where all the gas in the system has the same dew point.
Click here for Excel Spreadsheet This excel spreadsheet gives more details and more flexibility than the JavaScript Calculator. Also includes information on how to calculate mixing wet and dry gases to achieve a specific relative humidity.
Calculations of Current Density to Gas Flow
Under Construction. Coming soon
Calculations of Membrane Conductivity and Area Specific Resistance
Will guide the user through calculating conductivity and area specific resistance. Includes calculating a voltage drop for a given current density.
Historical Fuel Cell Units Converted to Current Standard Fuel Cell Units (ASF and mV/100ASF)
Guides the user through converting Amps per Square Foot (ASF) to mA/cm2. Also converts mV/100 ASF to mΩ*cm2
