Abstract
A fuel cell system for use in vehicles has a hydrogen electrode assembly, an oxygen electrode assembly, and a body of liquid electrolyte between the hydrogen electrode assembly and the oxygen electrode assembly. The hydrogen electrode assembly has a hydrogen sparger that releases fine bubbles of hydrogen gas into the electrolyte, and a hydrogen catalyst electrode having pores through which flow the electrolyte and bubbles of hydrogen gas.
Claims10
A fuel cell for generating electricity by reacting a gaseous fuel with oxygen, comprising:
- a fuel electrode assembly disposed within a housing and comprising a porous fuel catalyst electrode rotatable within the housing and a fuel sparger for introducing bubbles of a fuel into surrounding electrolyte;
- an oxygen catalyst electrode assembly disposed within said housing and comprising a porous oxygen catalyst electrode rotatable within the housing and an oxygen sparger for introducing bubbles of oxygen into surrounding electrolyte;
- and
- a body of fluid electrolyte within said housing in contact with the fuel electrode assembly and with the oxygen electrode assembly.
A fuel c ell for generating electricity by reacting a gaseous fuel with oxygen, comprising:
- a fuel electrode assembly disposed within a housing and comprising a porous fuel catalyst electrode rotatable within the housing and a fuel sparger for introducing bubbles of a fuel into surrounding electrolyte;
- an oxygen electrode;
- and
- a body of fluid electrolyte within said housing in contact with the fuel electrode assembly and with the oxygen electrode.
A fuel cell wherein a liquid electrolyte is flowed therethrough to consume a gaseous fuel, said fuel cell comprising:
