Fuel Cell System Having Water Vapor Condensation Protection

Abstract

A fuel cell system having protection from water vapor condensation is disclosed. The system includes a fuel cell having an input port configured to receive an input gas and a liquid water transient accumulation chamber coupled to the input port. The chamber is configured to accumulate condensed water vapor from the input gas. The chamber includes a water-capture element configured to retain liquid water therein. The system further includes a first thermal pathway coupled to the chamber and also coupled to the fuel cell, so that the chamber is heated by heat from the fuel cell, when the fuel cell is operating in a steady state, in a manner that causes the liquid water accumulated in the chamber to be evaporated by the heat.
