Abstract
A method for preparing a heat exchanger, comprising forming a moisture-permeable film having an air-impermeable function on a single side of a plate-shaped porous member to provide a gas-impermeable member for heat exchange, bonding a spacer corrugated for forming a fluid passage to a side of the gas-impermeable member with the moisture-permeable film formed thereon to provide a plurality of heat exchanger constituent elements, and layering the heat exchanger constituent elements so that the spacer in each of the heat exchanger constituent elements forms a fluid passage in each layer.
