“…The NTHS was tested and optimized in HySy-Lab laboratory and afterwards implemented on the vehicle prototype IDRA [12,24] that participated at the Shell Eco-Marathon competition [25] (Rotterdam-May 2015) achieving good results in terms of consumption. IDRA [26][27][28] (Figure 6a) is a carbon-fiber monocoque prototype [29,30] of 38 kg, 3 m length, 0.6 m height and 0.95 m width.…”

Humidity and temperature have an essential influence on PEM fuel cell system performance. The water content within the polymeric membrane is important for enhancing proton conduction and achieving high efficiency of the system. The combination of non-stationary operation requests and the variability of environment conditions poses an important challenge to maintaining optimal membrane hydration. This paper presents a humidification and thermal control system, to prevent the membrane from drying. The main characteristics of such a device are small size and weight, compactness and robustness, easy implementation on commercial fuel cell, and low power consumption. In particular, the NTHS method was studied in a theoretical approach, tested and optimized in a laboratory and finally applied to a PEMFC of 1 kW that supplied energy for the prototype vehicle IDRA at the Shell Eco-Marathon competition. Using a specific electronic board, which controls several variables and decides the optimal reaction air flow rate, the NTHS was managed. Furthermore, the effects of membrane drying and electrode flooding were presented.

The development of the chassis for the hydrogen fuel cell powered car has been involved in the designing and manufacturing aspects, while taking into consideration the mass, strength, stiffness, centre of gravity (COG), and manufacturing cost requirements. Towards this direction, a chassis design is proposed employing a space frame structure and constructed by an aluminium alloy with great strength. The structural design has been derived through the lightweight engineering approaches in conjunction with the part consolidation, Design for Assembly (DFA) and Design for Manufacture methods. Moreover, it has been performed in compliance with the safety regulations of the Shell Eco Marathon racing competition. The material's principal characteristics are the great strength, the low mass, as well as the great workability, machinability, and weldability. Following the national and global environmental issues, the recyclable characteristics of the aluminium alloy are an extra asset. Furthermore, the existence of aluminium alloy manufacturers around the fabricating area provides low cost supply and fast delivery benefits. The integration of the fuel cell powered vehicle is obtained through the designing and the manufacturing processes of the chassis and the parts fitted on the chassis. The manufacturing procedures are described thoroughly; mainly consisting of the cutting and welding processes and the assembling of the parts that are fitted on the chassis. Additionally, the proper welding parameters for the custom chassis design are investigated and are selected after deductive reasoning. The quality control of the weld joints is conducted by non-destructive methods (NDT) ensuring the required structural properties of the welds. A combination of the selected material, the specific type of the chassis, and the manufacturing processes lead to construction simplicity in a low manufacturing cost by using the existing laboratory equipment. Furthermore, the designing and manufacturing parameters lead to a stiff with a low centre of gravity, and the most lightweight chassis of the urban concept category at the Shell Eco Marathon race.

“…Polymer matrix composites are materials used both in the aeronautical and automotive industry to manufacture many different components. These materials are very sensitive to hygrothermal environments and this issue is quite relevant in different fields, such as vehicle production, sports vehicles, prototypes and will remain so until innovative solutions are found [1][2][3][4][5][6][7].…”

In this paper the influence of hygrothermal ageing on the chemical composition, as well as the mechanical and thermal properties of four different composite materials was investigated: woven carbon fibre and glass fibre, with traditional epoxy resin and advanced thermoplastic polyphenylene sulphide (PPS). In particular, hygrothermal tests of 500, 750 and 1000 hours are performed with standard cycling used by most of original equipment manufacturer and car manufacturers. The ultimate strength and Young′s modulus have been verified using tensile and compression tests. Infrared absorption and glass transition temperature were obtained via attenuated total reflectance‐dynamic mechanical thermal analysis combined testing. The glass transition temperature decreases in epoxy materials after ageing, while it increases in thermoplastic materials. The attenuated total reflectance analyses have shown a slight but irreversible change in the molecular structure of the epoxy matrix and at the fiber–matrix interface in polyphenylene sulphide composite materials. Finally, the results of the experiments give us useful suggestions for the design of vehicle structural components that are exposed to environmental conditions (rain, snow and humidity).
