Изобретение относитс  к области энергетики и может быть применено в тех случа х , когда необходим малогабаритный, недорогой источник энергии со значительной энергоемкостью, например, дл  электромобил .The invention relates to the field of energy and can be applied in cases where a compact, inexpensive energy source with significant energy consumption is needed, for example, for an electric vehicle.

Известен топливный элемент, содержащий в качестве топливного электрода щелочной металл, в частности литий, катод из индиферентного материала и окислитель-электролит из расплава солей.Known fuel cell containing as a fuel electrode an alkali metal, in particular lithium, a cathode of an indifferent material and an oxidizing electrolyte from molten salts.

Цель изобретени  - создание топливного элемента с более высокими удельными элетрическими характеристиками, повыщение его надежности и расширение диапазона ра бочих температур.The purpose of the invention is to create a fuel cell with higher specific electrical characteristics, increasing its reliability and expanding the range of operating temperatures.

Это достигаетс  тем, что в качестве окислител -электролита применена безводна  серна  кислота.This is achieved by using anhydrous sulfuric acid as an oxidizing electrolyte.

Топливный элемент содержит анод изThe fuel cell contains the anode of

щелочного металла, например лити , катод из индиферентного материала, наприм.ер молибдена , и в качестве окислител -электролита - безводную серную кислоту.alkali metal, for example lithium, a cathode of an indifferent material, for example molybdenum, and anhydrous sulfuric acid as an oxidizing electrolyte.

При замыкании внешней цепи на нагрузку электрохимической ионообменный проце между реагентами осуществл етс  через тонкую (несколько ангстрем) пассивирующую пленку, котора  образуетс  в момент контакта окислител -электролита ( О.) с металлическим горючим (t,L ).When the external circuit is closed on the load of the electrochemical ion-exchange process between the reagents, it is carried out through a thin (several angstroms) passivating film, which is formed at the moment of contact of the oxidizing electrolyte (O.) with the metallic fuel (t, L).

На аноде происходит окисление щелочного металлаAlkali metal oxidation occurs at the anode.

и т.д.etc.

Состав продуктов реакции зависит от степени разр да топливного элемента.The composition of the reaction products depends on the degree of fuel cell discharge.

Работа топливного элемента обусловлена установленньыи свойствами щелочных металлов - химической совл естимостью щелочных металлов с безводными окислител ми и электрохимическим взаимодействием щелочных металлов с безводными окислител ми-электролитами .The operation of the fuel cell is determined by the established properties of alkali metals — the chemical compatibility of alkali metals with anhydrous oxidizers and the electrochemical interaction of alkali metals with anhydrous oxidizing electrolytes.
