Abstract:

A compact cooling system for a vehicle includes an assembly of heat exchangers ( ), ( ), ( ) and ( ) connected to each other to provide a box-like configuration. Each heat exchanger ( ), ( ), ( ), ( ) includes a core with headers ( ), ( ) at each end in fluid communication with spaced, flattened tubes ( ) with fins (24) extending between the tubes in each of the cores. One of the cores ( ) is generally horizontal and located at the upper side of the box-like configuration. A radial discharge fan ( ) is located within the box-like configuration and receives cooling air and directs the same radially outwardly through the cores to cool fluid passing through the tubes ( ) of the cores. An equalization tank ( ), ( ) is mounted on the box-like configuration in overlying, spaced relation to a substantial portion of the surface of the heat exchanger ( ) so as to be in the path of cooling air merging from the heat exchanger ( ) to divert the same.

International Classification:

H01M008/04

US Classification:

429 26, 429 34, 429 39

Abstract:

Degradation of membranes in fuel cells due to dehydration by relatively dry incoming reactant gases is avoided through the use of a humidifier in the incoming reactant streams, At least one of the humidifiers is formed in a stack having alternating flow passages with the former receiving reactant gases and including fins therein and the latter receiving hot coolant from the fuel cell The fins in the flow spaces are provided with a hydrophilic coating to foster filmwise evaporation of water introduced through a nozzle The humidifier causes the reactant gas to attain a desired dewpoint before it is provided to the membranes of the fuel cell.
