FIELD: metallurgy.
SUBSTANCE: invention relates to hydrogen power engineering and may be used at hydrogen filling stations for future-technology motor transport running on fuel cells. Proposed cell comprises fuel-cell battery consisting of, at least, two units differing in quantity of fuel cells, each being provided with their separate pipelines with water feed valves and those to discharge from said units. Note here that oxygen is discharged beyond the casing while hydrogen is discharged therein. Said casing is divided into, at least, two different-strength sections by tight partition. Stronger section accommodates units with smaller cells. Method of operation comprises water feed into fuel-cell battery composed of two sections to decompose electrolysis gases, discharging the latter, cutting off supply of cells after reaching maximum tolerable pressure. Note here that hydrogen communication between two sections allows cut off, first, one section with larger quantity of cells in due time and, then, that with smaller quantity of cells.
EFFECT: optimised hydrogen generation, safe operation.
