초록

A fundamental problem which exists in fuel cells having an electrolyte that conducts oxygen ions, hydroxide ions or protons, is that of moistening air of combustion gases for preventing the electrolyte from drying out or thinning and thus preventing defective operation of the fuel cell during air operation. The construction and financial cost, in particular, for moistening of the air is of concern in such a device. In a low-temperature fuel cell, in particular a PEM fuel cell, and a method for moistening the electrolyte of the fuel cell, according to the...
