Characteristics of fuel cells under static and dynamic conditions

Szwajca Filip, Berger Andrew W., Spalletta Robert, Pielecha Ireneusz

Pojazdy Szynowe

2022

Nr 3-4

44--52

Modern internal combustion powertrains are the main source of propulsion for on-road and non-road vehicles. However, they are increasingly being replaced by electric or fuel cell-equipped alternative propulsion systems. The article presents a study of fuel cell characteristics operating under both static and dynamic conditions, with a 1.2 kW fuel cell set with a voltage converter and lead-acid batteries. In the conducted tests, the fuel cell stack's maximum efficiency reached 65%. Load tests (static and dynamic) have indicated higher fuel cell efficiencies when using hybrid operation with a DC/DC converter and battery.

The control of the working parameters of car hydrogen fuel cell stack in urban traffic conditions

Tyczka M., Skarka W.

Archives of Transport System Telematics

2016

Vol. 9, iss. 3

50--54

The paper describes the study of the control of the hydrogen fuel cell stack for a car, which has been prepared on the example of a light vehicle, built for racing competitions. The issue included of the control of the hydrogen cell stack in the conditions of varied energy demand, occurring during urban traffic and selection of system parameters, using numerical model.
