A Platinum‐Free Zero‐Carbon‐Emission Easy Fuelling Direct Hydrazine Fuel Cell for Vehicles

Abstract

Mach Platz, Platin: Eine Pt‐freie direkte Hydrazin‐Brennstoffzelle (DHFC), in der ein anionenaustauschender Polymerelektrolyt verwendet wird, zeigt eine maximale Krafterzeugung von 0.5 W cm−2 (1250 mA cm−2 bei 0.4 V). Ihre Leistungsfähigkeit ähnelt der der Wasserstoff‐Polymerelektrolyt‐Brennstoffzelle (PEFC) und ist weit besser als die der direkten Methanol‐Brennstoffzelle (DMFC).

Hydrazine electrooxidation on a composite catalyst consisting of nickel and palladium

“…Moreover, the DHFCs demonstrate a high electric motive force of 1.61 V (close to 1.64 V of the DBFCs, higher than 1.21 V of the DMFCs). Some catalysts for the HOR have been developed [3,[6][7][8][9][10][11][12][13]. It is reported that Pd is an effective catalyst [9,13].…”

Anode Catalysts for Direct Hydrazine Fuel Cells: From Laboratory Test to an Electric Vehicle

“…[1][2][3][4][5][6][7][8][9][10][11] Switching from acidic proton exchange to alkaline, anion-exchange membranes has many benefits, including: 1) fast fuel oxidation and oxygen reduction and 2) possible use of cheaper non-platinum group metal catalysts as anode and cathode material for both sides of the MEA. The materials show in both rotating disc electrode (RDE) and membrane electrode assembly (MEA) tests the world highest activity with peak current density of 16 000 A g À1 (RDE) and 450 mW cm À2 operated in air (MEA).…”

Theoretical Study on Hydrazine Chemisorption on Transition Metal Surfaces

“…Especially in the field of energy technology, hydrazine is a fuel for non-platinum alkaline based direct hydrazine fuel cell. 1,2) Hydrazine is also known as reduction agent in nanoparticle synthesis. 3,4) The development of the above mentioned technologies is often benefitted by the availability of information in atomic level of the involving processes.…”
