As background technology is introduced, fuel cell of the prior art relatively low is asked there are poor-performing and service life
Topic, the technical issues of in order to solve as above, applicant has carried out numerous studies to influencing fuel battery performance and the factor in service life,
And it has been surprisingly found that, kinetic current density (abbreviation current density) not only has relationship, but also with urging with the concentration of reaction gas
How much the dosage of agent has direct relation, and relationship therebetween directly affects performance and the service life of fuel cell.Herein
On the basis of, relationship of the present inventor between current density and catalyst amount has made intensive studies, and finds following
