Performance of a Printable Enzymatic Fuel Cell- Study on Mediated ThL Laccase Cathode

Enzyme catalyzed fuel cells offer potentially an inexpensive alternative to classical fuel cells, which rely on transition metals as catalysts. Due to the usage of biocatalysts, biofuel cells can be operated under mild conditions, i.e. near, or at room temperature and neutral pH. In addition the size of biofuel cells can be even 100 times smaller than a conventional battery or fuel cell, which enables the usage of biofuel cells in e.g. medical applications. [1, 2] One of the most interesting enzyme catalyzed fuel cells is a glucose/O2 biofuel cell due to its convenient, that is to say low-cost, renewable, safe and easily storable fuel. For an example, Sony has developed a glucose/O2 biofuel cell, the maximum power density of which is 1.5 mW/cm2 at 0.3 V [3]. They have demonstrated that biofuel cell assemblies can be used as
