WebVapor Concentration (Absolute Humidity) The vapor concentration or absolute humidity of a mixture of water vapor and dry air is defined as the ratio of the mass of water vapor M w to the volume V occupied by the mixture. D v = M w / V expressed in grams/m 3 or in grains/cu ft. The value of D v can be derived as follows from the equation PV = nRT. WebA concept of using the product water to internally humidify the air stream in a PEM fuel cell without external humidification is investigated by a simple, pseudo 2-D model along a single channel. This model takes into account the mass and energy balance, water and heat generation rates, heat removal, and water transport through the membrane.

WebFrom the relative humidity and saturation vapor pressure, we can find the actual vapor pressure. Then we can use the general law of perfect gases. In our case this is. where R is the universal gas constant defined as 8313.6, and Rv is the specific gas constant for water vapor defined as 461.5.
