Abstract
Official abstract text for this publication.
A system for the drying of exhaust gases from a fuel cell system includes two heat exchangers alternately exposed to an exhaust gas, which ice and accumulate water vapour from the exhaust gas by cooling through a coolant. A valve arrangement with a number of valves is adapted in such a manner that it operates one of the heat exchangers in an icing phase, in which the icing of water vapour is conducted, and the other heat exchanger in a regeneration phase, in which the accumulated ice melts and is extracted, in an alternating manner. This system is especially suitable in aircraft for drying an oxygen depleted exhaust gas from a fuel cell system for inerting a tank.
First claim
Opening claim text (preview).
The invention claimed is: 1. A system for drying of exhaust gases from a fuel cell system, comprising: at least one first heat exchanger; at least one second heat exchanger; a common exhaust gas inlet and a common exhaust gas outlet for the first and second heat exchangers; a common coolant inlet and a common coolant outlet for the first and second heat exchangers; a common air outlet for the first and second heat exchangers; a valve arrangement with a plurality of valve…
