The phrase "a closed cell" is correct and usable in written English.
It can be used in contexts related to biology, materials science, or architecture, referring to a cell that is sealed or not open to the environment.
Example: "The foam used in this product is made of a closed cell structure, which helps to prevent water absorption."
Alternatives: "an airtight cell" or "a sealed cell".
Overall, the freeze dried cakes behaved as neither classic closed cell nor open cell materials, with their compressive elastic moduli reflecting a closed cell elastic response whilst their failure stresses reflecting an open cell failure mode.
The samples were placed in a sample holder, and the sample holder placed in a closed cell with gas connections.
These sandwich panels consisted of two aluminium face-sheets and a closed cell aluminium foam core (ALPORAS®).
Perfect spherical morphology of non-graphitic carbon is prepared by heating mesitylene at 700 °C in a closed cell.
A closed cell was used to avoid possible deviations from equilibrium caused by vaporization of bismuth and oxides of bismuth.
The foams used in this study have a closed cell structure, with pores that are elliptical in shape.
Solitary confinement is one of the most abhorrent practices of our prison system, in which an inmate is kept in complete isolation for 22 to 24 hours a day in a closed cells for periods of time ranging from days to decades.

On polymerization, the microemulsions having a W/O droplet structure yielded solids with a closed-cell porous structure.
To be able to generate theoretical results for random models, the finite element method (FEM) was used to study the elastic properties of solids with a closed-cell cellular structure.
The PS homopolymer led to a homogeneous, closed cell structure, while the P4mS homopolymer did not foam at all.
