Abstract
An electrolytic cell includes a membrane electrode assembly, a pair of separators, a gas supply flow path, and a gas discharge flow path. A fuel electrode of the membrane electrode assembly contains a catalytic material that activates the electrolytic reactions of the raw material gas, and the amount of the catalytic material contained in the fuel electrode increases from the upstream side to the downstream side of the gas supply flow path.
Claims7
An electrolytic cell including:
- a membrane electrode assembly comprising a fuel electrode, an oxygen electrode, and an electrolyte membrane disposed between the fuel electrode and the oxygen electrode;
- pair of separators sandwiching the membrane electrode assembly;
- a gas supply flow path formed between the fuel electrode and one of the pair of separators along an electrode surface of the fuel electrode, a raw material gas to be supplied to the fuel electrode flowing through the gas supply flow path;
- and
- a gas discharge flow path formed between the oxygen electrode and another of the pair of separators along an electrode surface of the oxygen electrode, an oxygen gas generated at the oxygen electrode flowing through the gas discharge flow path,
- wherein the fuel electrode contains a catalytic material that activates electrolytic reactions of the raw material gas, and
- an amount of the catalytic material contained in the fuel electrode increases from an upstream side to a downstream side of the gas supply flow path.
