Abstract
A fuel cell system including a gas-diffusion electrode and a first passage means having at least one first section including a reforming catalyst and isolated in relation to the gas-diffusion electrode and at least one second section communicative in relation to the gas-diffusion electrode.
Claims22
An electrochemical cell system comprising:
- a gas diffusion electrode;
- a first passage means having a gas entry and gas exits ends and at least one first section and at least one second section therebetween, each said first section being an isolated section in relation to said electrode and each said second section being a communicative section in relation to said electrode;
- a catalyst for reforming hydrocarbons situated in at least a first one of said first sections, said first one of said first sections being closer to said gas entry end of said first passage means then a first one of said second sections.
An electrochemical cell system comprising:
- a gas diffusion electrode;
- a first passage means having gas entry and gas exits ends and at least one first section and at least one second section therebetween, each said first section being an isolated section in relation to said electrode and each said second section being a communicative section in relation to said electrode;
- a catalyst for reforming hydrocarbons situated in at least a first one of said first sections;
- and
- an electrolyte sink situated at an end of said first one of said first sections.

An electrochemical cell system comprising:
- a gas diffusion electrode;
- means adapted to receive an electrolyte so the electrolyte is in comnunication with the gas diffusion electrode, the electrolyte forming a film which creeps through the cell;
- a catalyst disposed in the cell for reforming fuel to produce fuel gas for the cell, there being a path for said electrolyte film to creep to said catalyst;
- and means in said path for increasing the length of said path.
