FIELD: power engineering.
SUBSTANCE: in fuel element, which comprises the following components: the first plate of fluid flow field; the second plate of fluid flow field; membrane electrode having the first and second opposite external surfaces placed between the first and second plates of fluid flow field; sealing gasket arranged between the first and second plates of fluid flow field and therefore shaping accordingly the first and second sealing surfaces; sealing gasket, also determinant third sealing surface, by means of which sealing gasket contacts only with one face surface of membrane electrode; according to invention, sealing gasket has zone of higher compressibility at the third sealing surface compared to the second sealing surface.
EFFECT: simplified assembly of fuel element and reduction of its cost.
