Guided by the assumptions resulting from the Polish Energy Policy until 2040 and the Act on electromobility, hydrogen may become an attractive form of long-term storage of electricity in the future. The article presents the possibilities of using fuel cell technology to generate heat and electricity. The principle of operation of a hydrogen cell was characterized. Existing solutions and trends in the development of this technology were presented. In addition, the financial and technological aspects of fuel cell technology were assessed. The use of fuel cells in a hybrid system is an effective way of storing electricity. Energy storage in the form of hydrogen is a new trend resulting from the advantages of generators converting energy stored in hydrogen, i.e. in fuel cells. Combustion of hydrogen in fuel cells does not emit any toxic gases, the efficiency of this process reaches 85%, the cells have a modular structure, their operation is noiseless and vibration-free.
