Title
(EN) HYBRID CYCLE SOFC - INVERTED GAS TURBINE WITH CO2 SEPARATION
(FR) CYCLE HYBRIDE SOFC - TURBINE À GAZ INVERSÉE AVEC SÉPARATION DU CO2
Abstract
(EN)
A new gas turbine-fuel cell Hybrid Cycle is proposed. The fuel cell advantageously operates close or under atmospheric pressure and is fully integrated with the gas turbine that is based on an Inverted Brayton-Joule Cycle. The idea of the invention is to capitalize on the intrinsic oxygen-nitrogen separation characteristic of the fuel cell electrolyte by sending to the Inverted Brayton-Joule Cycle only the anodic flow, which is the one free of nitrogen. In this way the flow that expands in the turbine consists only in steam and carbon dioxide. After the expansion the steam can be easily condensed, separated and pumped up. Therefore the compressor has mainly only to compress the separated carbon dioxide. This effect generates a substantial advantage in term of efficiency and enables separating the carbon dioxide. The new proposed Hybrid Cycle enables to: substantially increase the system efficiency compared to the known gas turbine-fuel cell Hybrid Cycle, maintain the fuel cell operating under or close to atmospheric pressure and separate the carbon dioxide.

L'invention concerne un nouveau cycle hybride turbine à gaz-pile à combustible. La pile à combustible fonctionne avantageusement à la pression atmosphérique ou proche de celle-ci, et est entièrement intégrée avec la turbine à gaz qui est basée sur un cycle de Brayton-Joule inversé. L'idée de l'invention consiste à capitaliser sur la séparation intrinsèque oxygène-azote caractéristique de l'électrolyte de la pile à combustible, en n'envoyant au cycle de Brayton-Joule inversé que l'écoulement anodique, c'est-à-dire celui qui est exempt d'azote. De cette façon, l'écoulement qui se détend dans la turbine est constitué uniquement de vapeur d'eau et de dioxyde de carbone. Après la détente, la vapeur d'eau peut être facilement condensée, séparée et remontée par pompage. Le compresseur n'a donc pour l'essentiel qu'à comprimer le dioxyde de carbone séparé. Cet effet génère un avantage substantiel en termes de rendement et permet la séparation du dioxyde de carbone. Le nouveau cycle hybride proposé permet : d'accroître sensiblement le rendement du système par comparaison au cycle hybride turbine à gaz-pile à combustible connu; de maintenir la pile à combustible en fonctionnement à la pression atmosphérique ou proche de celle-ci; et de séparer le dioxyde de carbone.
