ABSTRACT
The realization of a clean automobile society would require
electrically-powered propulsion systems in vehicles. In recent years, electric
vehicles have attracted considerable attention from the perspective of
utilizing electricity generated from natural sources, such as solar and wind
power. The propulsion method considered in the present investigation differs
from the conventional off-board energy scheme in a manner such that pure
stoichiometric H2/O2 fuels for fuel cells are generated
on-board during vehicle operation. In this method, energy conversion occurs by
means of ESI-PSE (electrostatic-induction potential-superposed electrolysis).
If a quasi-static process is assumed, the theoretical power requirement to
produce pure stoichiometric H2/O2 fuels is only 17% of
the total energy required owing to a new method for supplying power to the EC (electrolytic
cell). If an ESI-PSE EC is combined with a fuel cell (FC) to form an energy
cycle, a HREG (hydrogen redox electric power generator) that uses solid PEMs (polymer
electrolyte membranes) for the EC as well as the FC can be realized. According
to calculations based on data from the operational conditions of commercially
available ECs and FCs, more than 70% of the power delivered from the FC can be
extracted for driving a motor constantly while a car is in motion. Because of
energy self-sustainability on the HREG side, the power control system should
not have any power loss. This propulsion system will realize tough vehicles that
can continue running at a top speed at long unlimited cruising range.
