Abstract

Przedmiotem zgłoszenia jest sposób zarządzania ciepłem w wysokotemperaturowych ogniwach paliwowych, który polega na tym, że do kanałów ogniw paliwowych (II) wprowadza się wodę lub parę wodną (3) w temperaturze od 600°C do 1000°C, pod ciśnieniem atmosferycznym, za pomocą dysz wtryskowych (III) rozmieszczonych w kanałach ogniw paliwowych (II), gdzie temperatura stosu ogniw paliwowych (I) jest najwyższa, po czym woda zamienia się w parę wodną pochłaniając ciepło lub para wodna pochłania ciepło poprzez wzrost temperatury, obniżając temperaturę spalin wewnątrz kanałów ogniw paliwowych (II) do temperatury poniżej wartości krytycznych.The subject of the application is a method of heat management in high-temperature fuel cells, which consists in introducing water or steam (3) into the fuel cell channels (II) at a temperature of 600°C to 1000°C, at atmospheric pressure, by means of injection nozzles (III) arranged in the fuel cell channels (II), where the temperature of the fuel cell stack (I) is the highest, after which the water turns into steam, absorbing heat, or the steam absorbs heat by increasing the temperature, reducing the temperature of the exhaust gases inside the fuel cell channels (II) to a temperature below critical values.
