Abstract

A fuel cell installation includes a cascaded fuel cell block, for essentially waste gas-free operation. An installation of this type presents the problem that the cascaded fuel cell block is complex to produce and therefore expensive. To solve this problem, the fuel cell installation has several steps which are arranged in a cascade, each of the steps comprising one or more non-cascaded similar fuel cell blocks. A fuel cell installation construction including modular similar fuel cell blocks is economical and simple to produce in series.
