Description
前記目的を達成するため、本発明は、電極触媒層が両面に形成された固体高分子電解質の両面に酸素側集電体と水素側集電体が配され、前記酸素側集電体と水素側集電体の各外側に配置した分離体で、前記酸素側集電体と水素側集電体を挟持した構成を有し、水電解によって水素を製造する水素製造セルであって、前記水素側集電体は内部に有機的につながった多数の空隙を有しており、前記水素側集電体の外側に配置される分離体の前記水素側集電体側の表面は平坦であり、前記水素側集電体の外側に配置される分離体と前記水素側集電体との間には、電気分解の際に発生する反応流体の回収用の専用流路が形成されておらず、前記分離帯の表面と前記水素側集電体の表面とは直接密着しており、さらに前記分離帯の水素側集電体側の平坦な表面により、前記水素側集電体は前記固体高分子電解質に対して全面で圧接して接触していることを特徴としている。
かかる場合、前記水素側集電体は、カーボンペーパーまたはカーボン不織布で形成されていることが提案できる。また固体高分子電解質の材料は、フッ素系電解質膜、アルカリ系電解質膜または炭化水素系電解質膜のいずれかであってもよい。
In order to achieve the above-mentioned object, the present invention provides a hydrogen production cell which produces hydrogen by water electrolysis, comprising an oxygen-side current collector and a hydrogen-side current collector arranged on both sides of a solid polymer electrolyte having electrode catalyst layers formed on both sides thereof, and a separator arranged on the outside of the oxygen-side current collector and the hydrogen-side current collector sandwiching the oxygen-side current collector and the hydrogen-side current collector, wherein the hydrogen-side current collector has a large number of voids which are organically connected inside, the surface of the separator arranged on the outside of the hydrogen-side current collector facing the hydrogen-side current collector is flat, no dedicated flow path for recovering a reaction fluid generated during electrolysis is formed between the separator arranged on the outside of the hydrogen-side current collector and the hydrogen-side current collector, the surface of the separation band and the surface of the hydrogen-side current collector are in direct contact with each other, and further, the flat surface of the separation band facing the hydrogen-side current collector brings the hydrogen-side current collector into pressure contact with the solid polymer electrolyte over the entire surface thereof .
In such a case, it is suggested that the hydrogen-side current collector be formed of carbon paper or carbon nonwoven fabric. The material of the solid polymer electrolyte may be any one of a fluorine-based electrolyte membrane, an alkaline electrolyte membrane, and a hydrocarbon electrolyte membrane.
前記水素側集電体は長辺部と短辺部とを有する形状であり、前記回収部は、対向する長辺部側に各々形成されていることが好ましい。これによって、水素側集電体の内部を移動する際の圧力抵抗を減じて、速やかに回収することができる。
また、前記回収部は連通口であり、前記酸素側集電体の原料水入口、反応流体の出口となる各連通口は、前記水素側集電体の連通口よりも大きく設定されていることも提案できる。
前記酸素側集電体の外側に配置される分離体と前記酸素側集電体との間には、反応流体が流れる専用流路が形成されていてもよい。前記したようにこれら水素側集電体の空隙率は、５０％～９９％であるようにしてもよい、
It is preferable that the hydrogen-side current collector has a shape having long sides and short sides, and the recovery parts are formed on each of the opposing long sides, thereby reducing pressure resistance when moving inside the hydrogen-side current collector and enabling rapid recovery.
It can also be proposed that the recovery section is a communication port, and that the communication ports serving as the raw water inlet and the reaction fluid outlet of the oxygen side current collector are set larger than the communication ports of the hydrogen side current collector.
A dedicated flow path through which a reaction fluid flows may be formed between the oxygen-side current collector and a separator disposed outside the oxygen-side current collector. As described above, the porosity of these hydrogen-side current collectors may be 50% to 99%.
