Closed-cell polymeric foam for hydrogen separation and storage

Original language description

Closed-cell polystyrene foam was utilized as a membrane buffer for separation of (bio)hydrogen. In the foam the cell walls form a structured complex of membranes. The cells serve as pressure containers of separated gases. The foam membrane can buffer thedifference between the feed injection rate and the rate of consumption of the product. It can be utilized when biohydrogen feeds a fuel cell and consumption of electricity is not synchronous with hydrogen production. The function of the foam was assessed using a cubic model and the theoretical data were checked experimentally by using gases present in the bioreactor (H2,N2 and CO2). It turned out that there is a considerable difference (hundreds of minutes) in time-lags of various gases in the polymeric foam, thus the foam is able to separate hydrogen and also to store it effectively.

Polymerni pena pro separaci a skladovani vodiku)

Czech description

Polystyrenova pena byla pouzita jako membranovy buffer pro separaci biovodiku. Steny bunek peny tvori strukturovany komplex membran. Bunky slouzi jako tlakove kontejnery pro separovane plyny. Penova membrana muze vyrovnavat rozdil mezi rychlosti dodavkya spotreby plynu. Lze ji pouzit, kdyz biovodik zasobuje palivovy clanek a spotreba elektriny neni synchronizovana s vyrobou vodiku. Funkce peny byla popsana kubickym modelem a teoreticka data byla experimentalne overena pouzitim plynu pritomnych v bioreaktoru (H2, N2 a CO2). Ukazalo se, ze dochazi k vyraznemu rozdilu (ve stovkach minut) mezi casovymi zpozdenimi jednotlivych plynu v polymerni pene, tudiz penu lze s vyhodou pouzit k separaci a uchovani vodiku.
