Abstract
A fuel cell includes a positive electrode and a negative electrode which are opposed to each other with a proton conductor provided therebetween, and an enzyme immobilized as a catalyst on at least one of the positive and negative electrodes. In the fuel cell, the positive electrode, the proton conductor, and the negative electrode are accommodated in a space formed between a positive electrode current collector having a structure permeable to an oxidizer and a negative electrode current collector having a structure permeable to fuel.
