DISCRETELY SUPPORTED WET SIDE PLATES |
摘要 |
A water vapor transfer separator plate assembly and a method of making the same. In such an assembly made up of a stack of alternating wet side plates and dry side plates with a membrane disposed between them, a humid fluid such as that found in a fuel cell cathode exhaust flows against one side of each membrane such that at least some of its moisture content travels across the membrane to a lower humidity fluid on the opposite side of the membrane. The lower humidity fluid, such as that found in a fuel cell cathode entrance, experiences an increase in its humidity by the operation of the moisture flow across the membrane. At least a portion of the assembly may be made thinner by removing diffusion media and reinforcing structure of the dry side plates such that the overall assembly is simplified.
