“…According to that, in this work were performed experiments on the foam with same characteristics but improved with Ag coating on its surface. These measurements were carried out as the continuation of the previous work to define parameters which directly take effects on the electrolyser operation [13] Ammonia and acetic were used as a buffer to adjust the pH in the range from 10 to 10.6. In this solution metal ions of Ag were directly reduced into pure Ni foam by the involving of reducing agent of hydrazine-hydrate.…”

“…It is founding in forms of a bulk, the foam, a raney, a mesh and different alloys. The investigations for comparison of the bulk and pure foam have been already done where obtained results gave improved process using pure foam [13]. As the progressive continuation of that author's work, in this investigation experiments, both on the pure Ni foam and Ni foam silver (Ag) coated, were performed.…”

“…The oldest process for hydrogen production is the process of water electrolysis where the most important component of the system is the type of a chosen material for the electrodes design. Nickel (Ni) is a frequently used material in hydrogen generation process because of its good properties both as the catalyst and the electrode [11][12][13][14][15]. It is founding in forms of a bulk, the foam, a raney, a mesh and different alloys.…”

a b s t r a c tIn investigation of different materials for electrodes used in electrolysers for hydrogen production, nickel foam shows wide interests in hydrogen scientific community. This paper brings novel results of performed experiments on pure nickel foam and nickel foam silver coated. The electrochemical behavior of chosen material in high concentrated alkaline media was studied using potentiostatic and potentiodynamic DC and AC electrochemical methods: linear polarization, electrochemical impedance spectroscopy. It was shown that using silver coatings enable higher hydrogen generation. There is defined linear region of the hydrogen production with evidence that an increasing of the electrodes overvoltage decreases the resistance to the charge transfer.

“…It is important to highlight that hydrogen as a fuel is clean as much as is clean energy and processes used for its production. To satisfy this claim hydrogen production via water electrolysis using renewable energy sources is unquestionable (Đukić and Firak 2011). In Croatia there are around 1.9 millions vehicles.…”

Solar energy is a natural resource which can be harnessed to provide clean electricity for hydrogen production systems. However, this technology is not widely used because of control issues, particularly for hydrogen refuelling stations. At present, direct or DC-DC converter couplings are the most common system configurations for hydrogen refuelling stations. However, these system configurations are costly and suffer from gas shortage at hydrogen refuelling stations. Furthermore, the hydrogen produced by such system configurations varies considerably depending on the levels of solar radiation. In order to address these issues, a new system configuration is proposed, incorporating the feedback signal of the storage level in the control system. The photovoltaic (PV) system, electrolyzer, and storage tank are integrated with a fuzzy logic controller (FLC) to determine the backup current compensation for electrolyzer operation in order to obtain the minimum power required for hydrogen production. The proposed FLC is constructed with three input variables which are the PV current, hydrogen storage level, and the battery state of charge. The rules-based fuzzy inference process is based on the proposed configuration which combines the advantages of direct and DC-DC converter coupling configurations. The simulation results show that the proposed configuration offers better adaptability to variable radiation conditions compared to other methods. This gives a more promising option for ensuring the adequacy of hydrogen supply at hydrogen refuelling stations.
