Fuel cell i.e. high-temperature polymer electrolyte membrane fuel cell, system for generation of e.g. current, has blower supplying residual gas burner with oxidant, and bypass valve discharging partial flow of cathode exhaust gas stream

摘要

The system has a reformer (1) converting gaseous hydrocarbon e.g. propane or natural gas. A high-temperature polymer electrolyte membrane (HT-PEM) fuel cell is provided with an anode- and cathode space with carbon monoxide tolerance. A product gas generated in the reformer is supplied into heat exchangers (10, 20) of an anode (2) of the fuel cell over a connection line (7). Anode exhaust gas is guided into a residual gas burner over one of the heat exchangers. A blower (21) supplies the burner with oxidant, and a bypass valve discharges a partial flow of a cathode exhaust gas stream. An independent claim is also included for a method for regulation and controlling of a fuel cell system.
