FUEL CELL, FUEL CELL SYSTEM, AND ELECTRONIC DEVICE

摘要

Provided is a fuel cell capable of eliminating affects of gravity by using a simple configuration and obtaining high-energy density by suppressing crossover. An electrolyte channel (30) is provided for flow of a first fluid F1 containing an electrolyte between a fuel electrode (10) and an oxygen electrode (20). A fuel channel (40) for flow of a second fluid F2 containing fuel is provided outside the fuel electrode (10). The fuel electrode (10) has a function of a separation film separating the electrolyte from the fuel, thereby enabling generation of electricity not depending on a position of a fuel cell (110). A reaction occurs when almost entire fuel passes through the fuel electrode (10) and the fuel crossover is significantly suppressed. Accordingly, it is possible to use a high-concentration fuel and use the advantage of the high-energy density characteristic. When a gas/liquid separating film is arranged between the fuel channel (40) and the fuel electrode (10), it is also possible to use pure methanol and obtain a further higher energy density.
