“…Regarding the enzyme immobilization strategy, although physical adsorptions like physical entrapment and chemical bonding like covalent coupling and enzyme cross-linking were attempted, using Layer-by-Layer (LbL) has been recently emerged. According to the LbL structure, (i) multiple repetitive layers are stack together by electrostatic interaction between oppositely charged species and (ii) the stack layers are formed on the nano-sized supporters like carbon nanotube (CNT) 2 10 11 12 13 .…”

Mediatorless and membraneless enzymatic biofuel cells (EBCs) employing new catalytic structure are fabricated. Regarding anodic catalyst, structure consisting of glucose oxidase (GOx), poly(ethylenimine) (PEI) and carbon nanotube (CNT) is considered, while three cathodic catalysts consist of glutaraldehyde (GA), laccase (Lac), PEI and CNT that are stacked together in different ways. Catalytic activities of the catalysts for glucose oxidation and oxygen reduction reactions (GOR and ORR) are evaluated. As a result, it is confirmed that the catalysts work well for promotion of GOR and ORR. In EBC tests, performances of EBCs including 150 μm-thick membrane are measured as references, while those of membraneless EBCs are measured depending on parameters like glucose flow rate, glucose concentration, distance between two electrodes and electrolyte pH. With the measurements, how the parameters affect EBC performance and their optimal conditions are determined. Based on that, best maximum power density (MPD) of membraneless EBC is 102 ± 5.1 μW · cm−2 with values of 0.5 cc · min−1 (glucose flow rate), 40 mM (glucose concentration), 1 mm (distance between electrodes) and pH 3. When membrane and membraneless EBCs are compared, MPD of the membraneless EBC that is run at the similar operating condition to EBC including membrane is speculated as about 134 μW · cm−2.

9The paper provides a performance analysis assessment of a novel solid oxide fuel cell 10 (SOFC) liquid desiccant tri-generation system for building applications. The work 11 presented serves to build upon the current literature related to experimental evaluations 12 of SOFC tri-generation systems, particularly in domestic built environment applications. 13The proposed SOFC liquid desiccant tri-generation system will be the first-of-its-kind. No 14 research activity is reported on the integration of SOFC, or any fuel cell, with liquid 15 desiccant air conditioning in a tri-generation system configuration. The novel tri-16 generation system is suited to applications that require simultaneous electrical power, 17 heating and dehumidification/cooling. There are several specific benefits to the integration 18 of SOFC and liquid desiccant air conditioning technology, including; very high operational 19 electrical efficiencies even at low system capacities and the ability to utilise low-grade 20 thermal energy in a (useful) cooling process. Furthermore, the novel tri-generation system 21 has the potential to increase thermal energy utilisation and thus the access to the benefits 22 achievable from on-site electrical generation, primarily; reduced emissions and operating 23 costs. Compared to an equivalent base case system, the novel tri-generation system is currently 34 only economically viable with a government's financial support. SOFC capital cost and 35 stack replacement are the largest inhibitors to economic viability. Environmental 36 performance is closely linked to electrical emission factor, and thus performance is heavily 37 country dependent. (4) The economic and environmental feasibility of the novel tri-38 generation system will improve with predicted SOFC capital cost reductions and the 39 transition to clean hydrogen production. 40 41
