Embodiment Construction

[0035] figure 1 The fuel cell system 2 according to the invention is shown in a schematic block diagram. The core component is the fuel cell stack 4 comprising a number of individual low temperature fuel cells, eg PEM fuel cells, arranged in groups and electrically connected to each other in series and / or parallel. The fuel cell stack 4 includes a hydrogen inlet port 6 , an oxygen inlet port 8 , an exhaust outlet port 10 and a purge gas outlet port 12 . The hydrogen inlet port 6 is coupled with the hydrogen inlet 14 of the fuel cell system 2 . However, the hydrogen inlet port 6 can also constitute the hydrogen inlet 14 itself. The oxygen inlet port 8 is coupled with an air separator 16 comprising an oxygen outlet port 18 , an inert gas outlet port 20 and an air inlet port 22 . The air inlet port 22 of the air separator 16 is coupled with a compressor 24 that compresses air delivered through an air inlet 26 of the fuel cell system 2 . The air separator 16 provides substanti...

Abstract

A fuel cell system (2) comprises an air inlet (26), a hydrogen inlet (14), an inert gas outlet (27), a water outlet (38), an electrical power outlet (32), at least one low temperature fuel cell (4) and at least one air separator (16). The air separator (16) is positioned between the air inlet (26) and a cathode of the at least one fuel cell (4) and is adapted for separating oxygen from the air and feeding the oxygen to a cathode of the at least one fuel cell (4). The fuel cell (4) is capable of delivering liquid water as a by-product due to the use of substantially pure oxygen and hydrogen in a low temperature operation, such that extraction and condensation requiring cooling capacity is not necessary. The fuel cell system (2) is therefore efficient and compact.

Description

technical field [0001] The invention relates to a fuel cell system, a method for operating a fuel cell and a vehicle with the fuel cell system. technical background [0002] The use of fuel cells in vehicles for performing a number of different tasks, such as supplying electrical energy, water, nitrogen-enriched air, and heat, is a known method for increasing fuel efficiency and reducing noise emissions. In particular, the use of fuel cells in aircraft has great potential for significantly reducing fuel consumption and replacing auxiliary power sources based on gas turbine engines. [0003] In conventional general purpose fuel cell systems in aircraft (these battery systems are not aimed at generating electricity in emergency situations), air and oxygen are used as oxidant and fuel. When hydrogen is supplied to the anode and air is supplied to the cathode, fuel cell processing occurs during which the oxygen content of the air reacts with the hydrogen so that the air is depl...
