Here we present an autonomous implantable device for vasopressin monitoring and prevention of latephase hemorrhagic shock powered using a novel non-enzymatic fuel cell unit. The device consists of a biosensor, drug delivery device and fuel cell unit. The innovative stacked single-layer fuel cell (SLFC) design allows to achieve small packaging volume and reduces oxygen cross-over at the anode re...

The paper focuses on the conductivity of the fuel cell electrolyte in a membraneless glucose-fueled alkaline fuel cell. The electrolyte conductivity is interpreted using simple physical models, considering either the empirical behavior of the solution’s viscosity, or the consideration of ions and molecules colliding in solutions. The conductivity is expressed as a function of KOH and glucose co...

Neutral red (NR) was utilized as an electron mediator in microbial fuel cells consuming glucose to study both its efficiency during electricity generation and its role in altering anaerobic growth and metabolism of Escherichia coli and Actinobacillus succinogenes. A study of chemical fuel cells in which NADH, NR, and ferricyanide were the electron donor, the electronophore, and the electron acc...

Biofuel cells (BFCs), which use enzymes as catalysts to harvest energy from green and sustainable fuels abundantly producible from biological systems, are promising next-generation energy devices. However, the poor stability and high specificity to only one fuel type of these bio-catalysts largely limits the practical use of current BFCs. In this contribution, we demonstrate a unique fuel cell ...

An enzyme fuel cell employing a carbon cloth electrode and bacterial FAD dependent glucose dehydrogenase (FADGDH) based on the direct electron transfer principle was constructed, and its scalability and cellulolytic sugar conversion were investigated. FADGDH was immobilized on the carbon cloth electrode together with carbon paste to form a multi-module type enzyme fuel cell by combining platinu...

5'AMP-activated protein kinase (AMPK) can be activated in response to cellular fuel depletion and leads to switching off ATP-consuming pathways and switching on ATP-regenerating pathways in many cell types. We have hypothesized that AMPK is a central mediator of insulin-independent glucose transport, which enables fuel-depleted muscle cells to take up glucose for ATP regeneration under conditio...

Acid-mine drainage (AMD) is difficult and costly to treat. We investigated a new approach to AMD treatment using fuel cell technologies to generate electricity while removing iron from the water. Utilizing a recently developed microbial fuel cell architecture, we developed an acid-mine drainage fuel cell (AMD-FC) capable of abiotic electricity generation. The AMD-FC operated in fed-batch mode g...
