Device for the transfer of water and heat between two air flows and use thereof for the humidification of fuel cell inlet gas

摘要

The invention relates to a device for the transfer of water and heat between a first and a second air flow. The inventive device consists of a stack of at least two transfer sub-assemblies having a lamellar configuration, each sub-assembly comprising a two-layer transfer structure with hydrophilic porous materials (3, 4), which is disposed between a first structure for the distribution of the first air flow (1) and a second structure for the distribution of the second air flow (2).

主权项

1. A device for transferring water and heat between a first air flow and a second air flow, comprising a stack of at least two transfer subassemblies having a lamellar configuration, each of said transfer subassemblies comprising:
a first structure comprising channels for distributing the first air flow; a second structure comprising channels for distributing the second air flow; one macroporous hydrophilic layer; and two microporous hydrophilic layers, wherein said one macroporous hydrophilic layer is sandwiched between said two microporous hydrophilic layers to form a three-layer structure and said three-layer structure is sandwiched between said first and second structures.
