Biomaterials are known to be useful in the medical
and electrical fields. In the field of energy devices,
biomaterials are also attractive materials leading a
sustainable society, because these materials are abundant
in the natural world and have a potential for the realization
of zero emissions. Especially, ion generation and ion
transport system with tissue-derived biomaterials are
useful for energy sources such as fuel cells. Therefore,
research on proton transport based on biomaterials is
significantly important to realize a hydrogen energy society
in which environmental loads can be responsibly reduced,
and thus the investigations of new proton sources and/or
new proton-transport materials based on biomaterials are
strongly desired. It is known that biomaterials are exhibit
proton transport using the mechanism of proton channel,
proton pomp and water crosslinking. Recently, we have
fabricatedbio-basedfuelcellsusingtheelectrolyteoftissue-
derived biomaterials such as DNA, collagen and chitin, and
we have found that biomaterials can be utilization as the
electrolyte of fuel cells. These results indicate that the
biomaterial becomes proton conductor. By impedance
analyses, collagen, which is one of tissue-derived
biomaterials, shows relatively high proton conductivity of
10-2 S/m in the humidified condition. Further, the power
density in the fuel cell based on collagen electrolyte is
approximately 10W/m 2 and we have found that these bio-
based fuel cells light the LED. In the present talk, we will
show the characteristics feature of bio-based fuel cells
based on the electrolyte of tissue-derived biomaterials and
will mainly discuss the mechanism on proton conductivity
in tissue-derived biomaterials. In addition to these results,
we will talk about proton sources based on biomaterials.
Speaker Biography
Yasumitsu Matsuo is a professor in Setsunan University and the
chairperson of Department of Life Science in Faculty of Science &
Engineering. He has taken a doctorate on science by photoconductivity in
GeO 2/Ge bilayer film and thereafter has also investigated the mechanism
of proton conductivity in hydrogen-bonded superprotonic conductors.
Especially, he has found that superprotonic conductivity in hydrogen-
bonded materials is realized by the competition between strain energy
and proton kinetic energy including the entropy term. Currently he
conducts research on not only superprotonic conductors but also proton
conductors based on biomaterials. More recently, he has fabricated
the fuel cell based on the tissue derived biomaterials and made clear
the mechanism of proton conductivity in the humidified biopolymer.
In addition, very recently, he has proposed new proton sources using
biomaterials and contributes the development of hydrogen energy field
as an officer in the Solid-State Ionics Society of Japan.
