Existing plate-type heat exchangers typically include plates that are constructed of metal or paper, which are only capable of transferring a limited amount of moisture, if any, from one side of the plate to the other side. The present invention is a plate-type heat exchanger wherein the plates are constructed of ionomer membranes, such as sulfonated or carboxylated polymer membranes, which are capable of transferring a significant amount of moisture from one side of the membrane to the other side. Incorporating such ionomer membranes into a plate-type heat exchanger provides the heat exchanger with the ability to transfer a large percentage of the available latent heat in one air stream to the other air streams. The ionomer membrane plates are, therefore, more efficient at transferring latent heat than plates constructed of metal or paper.

What is claimed is: 1. An energy recovery ventilator having a separator between a first passageway and a second passageway for a first gas stream and a second gas stream to pass therethrough, respectively, said separator comprising an at least partially sulfonated random hydrocarbon copolymer ionomer membrane, and further comprising: a three-dimensional structure disposed in at least one said passageway to maintain said passageway open. 2. The energy recovery ventilator as recited in claim 1, wherein said three-dimensional structure comprises a plurality of uniformly stacked pyramids. 3. The energy recovery ventilator as recited in claim 1, wherein said three-dimensional structure induces stirring in said gas stream flowing in said passageway, thereby increasing the effectiveness factor of said plate-type heat exchanger. 4. The energy recovery ventilator as recited in claim 1, wherein said three-dimensional structure comprises a plurality of spacer bars. 5. An energy recovery ventilator having a separator between a first passageway and a second passageway for a first gas stream and a second gas stream to pass therethrough, respectively, said separator comprising an at least partially sulfonated random hydrocarbon copolymer ionomer membrane, and further comprising: a substantially two-dimensional reinforcement structure associated with said membrane to support said membrane. 6. The energy recovery ventilator as recited in claim 5, wherein said substantially two-dimensional reinforcement structure comprises a two dimensional trigonal structure. 7. The energy recovery ventilator as recited in claim 5, wherein said substantially two-dimensional reinforcement structure comprises a sheet of webbed netting. 8. The energy recovery ventilator as recited in claim 5, wherein said substantially two-dimensional reinforcement structure comprises a layer of plastic. 9. The energy recovery ventilator as recited in claim 8, wherein said layer of plastic comprises a selected one of polytetrafluroethylene, expanded polytetrafluroethylene, polypropylene, and an open cell polymer film.
