Highly efficient drivetrains can be developed based on PEFC technology and curb weight may be limited by an innovative vehicle construction. In this paper, data on consumption and efficiency of a four‐place passenger vehicle with a curb weight of 850 kg and an H2/O2 fed PEFC/Supercap hybrid electric powertrain are presented. Hydrogen consumption in the New European Driving Cycle is 0.67 kg H2/100 km, which corresponds to a gasoline equivalent consumption of 2.5 l/100 km. When including the energy needed to supply pure oxygen, the calculated consumption increases from 0.67 to 0.69–0.79 kg H2/100 km, depending on the method of oxygen production.","lang":"eng"}],"year":"2007","citation":{"ieee":"F.

The efficiency of a hydrogen/oxygen polymer electrolyte fuel cell system is analyzed and compared to hydrogen/air systems. The analysis is performed for the tank to electric power chain.

The results show that if hydrogen is produced from primary fossil energy carriers, such as natural gas and pure oxygen needs to be obtained by a conventional process; the fuel to electric current efficiency is comparable for hydrogen/oxygen and hydrogen/air systems.

Therefore, a new concept, with passive process air humidification integrated into the stack, has been developed. Humidification in each cell makes the process independent from the number of cells and the operation mode, thus making the concept fully scalable. Without external humidification the system is simpler, smaller, and cheaper. The humidification of the process air is achieved by transfer of product water from the exhaust air, through part of the membrane, to the dry intake air. Tests have shown that cells using the concept of internal humidification and operated with dry air at 70 ° have almost the same performance as when operated with external humidification. A 42‐cell stack with this internal humidification concept was built and integrated into a portable 1 kW power generator system."}],"doi":"10.1002/fuce.200400028","day":"01","publication_identifier":{"issn":["1615-6846","1615-6854"]},"extern":"1","status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","volume":4,"author":[{"full_name":"Santis, M.","last_name":"Santis","first_name":"M."},{"last_name":"Schmid","first_name":"D.","full_name":"Schmid, D."},{"first_name":"M.","last_name":"Ruge","full_name":"Ruge, M."},{"id":"A8CA28E6-CE23-11E9-AD2D-EC27E6697425","last_name":"Freunberger","first_name":"Stefan Alexander","full_name":"Freunberger, Stefan Alexander","orcid":"0000-0003-2902-5319"},{"last_name":"Büchi","first_name":"F.N.","full_name":"Büchi, F.N."}],"issue":"3","publication":"Fuel Cells","_id":"7333","month":"08","title":"Modular stack-internal air humidification concept-verification in a 1 kW stack","intvolume":"         4","publication_status":"published","oa_version":"None","date_created":"2020-01-15T12:24:14Z","article_processing_charge":"No","language":[{"iso":"eng"}],"page":"214-218","quality_controlled":"1","article_type":"original","publisher":"Wiley"}]
