Energies based on biomaterials attract a lot of interest as next-generation energy because biomaterials are environmentally friendly materials and abundant in nature. Fuel cells are also known as the clean and important next-generation source of energy. In the present study, to develop the fuel cell based on biomaterials, a novel biofuel cell, which consists of collagen electrolyte and the hydrogen fuel generated from photochemical system II (PSII) in photosynthesis, has been fabricated, and its property has been investigated. It was found that the PSII solution, in which PSII was extracted from the thylakoid membrane using a surfactant, generates hydrogen by the irradiation of light. The typical hydrogen-generating rate is approximately 7.41 × 1014 molecules/s for the light intensity of 0.5 mW/cm2 for the PSII solution of 5 mL. The biofuel cell using the PSII solution as the fuel exhibited approximately 0.12 mW/cm2. This result indicates that the fuel cell using the collagen electrolyte and the hydrogen fuel generated from PSII solution becomes the new type of biofuel cell and will lead to the development of the next-generation energy.

“…The electrolyte layer remains an electronic insulator at all temperatures and provides a gas tight layer avoiding cross-leakage of fuel or oxidant. Moreover, the electrolyte material is stable to both reducing and oxidizing environments other than presenting good mechanical and thermal stability characteristics (provided that thermal expansion coefficients of anode, cathode and electrolyte are compatible) [26]. Following the fuel flow (here assumed as only hydrogen for simplicity), H 2 flows through the porous anode compartment (typically constituted of Ni with additional YSZ to increase the Triple Phase Boundary "TPB" (regions where gas, electronic conducting phase and ionic conducting phase coexist, named) [11] and avoid Ni grain growth [27]) where it is diffused from the bulk layer towards the functional layer at the electrode-electrolyte interface (TPB region); here H 2 is oxidized in the catalytic active sites by the O 2− ions releasing electrons in an external electrical circuit (anode semi-reaction, Equation (1)).…”

Solid Oxide Fuel Cells are a promising technology for Solid Oxide Fuel Cells (SOFC) are a promising technology For high-efficiency electrochemical conversion of a vast range of fuel gas mixtures, thigh operating temperature conditions (650–900 °C) represent a challenge both at system level and at laboratory testing level, in terms of material properties and performance dynamics. In this work a detailed procedural analysis is presented for an innovative all-ceramic compact SOFC test rig and first experimental testing results are reported in terms of polarization curves obtained under parametric variation of operating conditions (H2 content, air ratio λ and temperature) and short-term voltage stability test under load (140 h at 0.3 A/cm2). The electrochemical characterization results confirm the validity of the used all-ceramic cell holder, showing excellent cell performances in terms of polarization. H2 content has the most impact on SOFC performance, followed by temperature and finally air ratio, whose impact in the analyzed range is hardly seen. From the short-term stability test, the test bench setup reliability is demonstrated, showing no significant performance degradation after 140 continuous hours under load, which confirms the high quality and reproducibility of the results.

“…The development of solid oxide fuel cells (SOFCs) capable of generating electricity by means of a single-step electrochemical approach has been an urgent task since the mid-nineteenth century. Currently, considerable efforts have been devoted to the study of both individual materials (electrolytes, anodes, cathodes, collectors, sealants) and the design and testing of SOFCs [ 1 , 2 , 3 ]. It is now extremely important to scale-up from laboratory activity to commercial device.…”

Undoped Sr2MMoO6 Double Perovskite Molybdates (M = Ni, Mg, Fe) as Promising Anode Materials for Solid Oxide Fuel Cells

et al. 2021

View full text Add to dashboard Cite

The chemical design of new functional materials for solid oxide fuel cells (SOFCs) is of great interest as a means for overcoming the disadvantages of traditional materials. Redox stability, carbon deposition and sulfur poisoning of the anodes are positioned as the main processes that result in the degradation of SOFC performance. In this regard, double perovskite molybdates are possible alternatives to conventional Ni-based cermets. The present review provides the fundamental properties of four members: Sr2NiMoO6-δ, Sr2MgMoO6-δ, Sr2FeMoO6-δ and Sr2Fe1.5Mo0.5O6-δ. These properties vary greatly depending on the type and concentration of the 3d-element occupying the B-position of A2BB’O6. The main emphasis is devoted to: (i) the synthesis features of undoped double molybdates, (ii) their electrical conductivity and thermal behaviors in both oxidizing and reducing atmospheres, as well as (iii) their chemical compatibility with respect to other functional SOFC materials and components of gas atmospheres. The information provided can serve as the basis for the design of efficient fuel electrodes prepared from complex oxides with layered structures.
